Evening all! Sports Mole's live 2018 World Cup coverage continues from Kazan as Iran face Spain in Group B. Iran opened their tournament with a 1-0 win over Morocco last time out, while Spain drew 3-3 with Portugal in what was a spectacular match. Portugal actually moved to the top of Group B with a 1-0 victory over Morocco earlier this afternoon, and there is certainly pressure on both Iran and Spain to pick up a positive result in this match. Stay tuned for the action!

Tonight will be the first ever meeting between Iran and Spain in international football, and the former will be looking to cause a shock to book their spot in the last-16 stage of the competition. Right, without further ado, let me bring you up-to-speed with the all-important team news here...

TEAMS!

IRAN: Beiranvand; Haji Safi, Pouraliganji, Hosseini, Ramin; Taremi, Ezatolahi, Omid, Amiri, Karim; Sardar

SPAIN: De Gea; Carvajal, Pique, Ramos, Alba; Busquets, Iniesta; Silva, Isco, Vazquez; Costa

Interim Spain boss Fernando Hierro has made two changes to the team that started against Portugal last time out, with fit-again Dani Carvajal and Lucas Vazquez coming in for Nacho and Koke. Diego Costa scored twice against Portugal and keeps his spot, while Andres Iniesta will operate in a deeper position. David Silva and Isco also retain their positions in the La Roja XI.

Gerard Piqué wins his 100th cap for Spain tonight. A legend for La Roja, whether some supporters like it or not... #Piqué100 #ESP #WorldCup

As for Iran, head coach Carlos Quieroz has made three changes to the team that started the 1-0 win over Morocco last time out. Majid Hosseini, Mehdi Taremi and Saeid Ezatolahi are all included, while Sardar Azmoun - the leading scorer in the squad - keeps his spot at the tip of the attack.

There is no question that Iran will be looking to Azmoun for inspiration tonight, with the Rubin Kazan forward netting 23 times in 34 appearances for his country. There are plenty of goals in this Iran side when considering that Mehdi Taremi also starts, while Karim Ansarifard also keeps his position in the team. Nottingham Forest midfielder Ashkan Dejagah, however, is again on the bench.

So there we have it. The two teams are in, and we are now just about 40 minutes from kickoff in Kazan. As mentioned, Portugal moved to the top of Group B with a 1-0 victory over Morocco earlier this afternoon, and there is certainly pressure on both Iran and Spain to pick up a positive result in this match. A victory for Iran would actually take them into the knockout round of the tournament.

Iran's clash with Morocco last week was not exactly a classic, but a 95th-minute own goal from Aziz Bouhaddouz saw Quieroz's side pick up all three points. Team Melli have never been past the group stage of a World Cup, but another win tonight would take them into the knockout round.

Iran won six of their 10 qualification matches to make this summer's finals – only conceding two goals in the process. They were tight defensively against an attacking Morocco team last time out, and Spain will have a job on their hands to breach Iran's back four in this match.

As mentioned, Spain opened their tournament with a 3-3 draw against Portugal last time out. The 2010 world champions trailed 1-0 and 2-1 before leading 3-2, but a late Cristiano Ronaldo free kick saw Portugal claim a point. As a result, there is pressure on La Roja to pick up a win here.

..... Spain, for me. However, Iran are certainly capable of causing a shock here.

Spain would join Portugal on four points with a win tonight, but Iran would still be on three points, and qualification would go to the final matchday. Portugal will face Iran in what looks to be a hugely important match, while Spain will finish against Morocco, who have already been eliminated. That said, Morocco played extremely well in their 1-0 defeat to Portugal in Moscow.

Spain lifted the 2010 World Cup, but were incredibly eliminated in the group stage of the competition back in 2014. It would be a huge surprise if La Roja did not make it through this section when all is said and done, but their preparations in Russia were not exactly ideal when considering that Julen Lopetegui was sacked just one day before the start of the tournament.

Indeed, Lopetegui was confirmed as Real Madrid's new boss last Tuesday, but the president of the Spanish FA Luis Rubiales claimed that the decision was made without his knowledge. The RFEF was unable to accept Lopetegui's handling of the situation, and relieved him of his duties. As a result, former Spain and Real Madrid centre-back Fernando Hierro is currently in charge.

Here we go then; both sets of players have joined us on the pitch ahead of kickoff in Kazan. A win for Iran takes them into the knockout round of the competition, and would leave Spain in a very tough spot. It should be a very interesting game of football; stay tuned for live updates!

KICKOFF! Spain kick things off in this Group B clash...

... it must be said that there is a wonderful atmosphere inside the stadium tonight. Spain will dominate the ball, but Iran will be very tough to break down. The noise really is deafening here.

The match has not really got going in the opening four minutes, with a series of late challenges forcing the referee to intervene. The crowd are yet to settle, meanwhile, as the noise continues.

Positive goalkeeping from Beiranvand as the Iran stopper comes through a crowd of players to punch clear a cross from Carvajal. Spain have a half-chance moments later when Carvajal meets a deep cross, but the right-back's effort was always rising high and wide of the Iran crossbar.

Iran win a free kick in a wide position as Amiri is bundled to the ground...

... super header from Pique to clear the first cross, and Amiri then fires high and wide of the crossbar. Well, Iran are certainly up for this match, and the same can be said for their fans.

Azmoun receives some treatment following a heavy challenge from Ramos. Accidental? Well it was Ramos so! Nine minutes on the clock, and this one is bubbling along very nicely indeed.

Alba delivers a dangerous cross into the Iran box, but neither Ramos nor Pique can direct the ball towards goal. No sign that the deafening noise inside the stadium is going to be dampened!

Azmoun catches Busquets with a very late challenge, and the referee is tested.

Half-chance for Iran as Azmoun finds space in a forward position, but his effort was always wide.

The match is not in any sort of rhythm at the moment as the referee continues to intervene. We are still waiting for the first opportunity, with 16 minutes now on the clock in Kazan.

Taremi manages to break the offside flag, but the number 17 does not make the most of the situation, and Spain get away with one there. Iran are not here to sit deep, that is for sure.

David Silva finds some space in a forward position, but the midfielder's strike is straight into an Iran shirt. Spain are finding it difficult to pick their passes in the final third of the field here.

Iran continue to clear their lines, with Spain simply unable to pick their passes in the final third. There is no question that Carlos Quieroz has drilled this Iran side incredibly well.

Ramos's free kick hits the Iran wall before Beiranvand collects. Iran look to break, but they do not have the bodies forward, and Spain quickly win another free kick in a fairly advanced area...

... Ezatolahi is still down receiving treatment for Iran after a little clash with Costa.

Silva's free kick is straight into the arms of the Iranian goalkeeper.

It is very much an attack versus defence exercise at the moment, but Spain will not become frustrated. Indeed, the 2010 world champions will fancy their chances of picking a pass at some point tonight. That said, Iran have players capable of causing problems on the counter-attack.

Pass, pass, pass from Spain as they look to pick a way through this stern Iran defence.

Wonderful passing move from Spain as Isco scoops the ball into Iniesta, but Iran have enough players back to make the clearance. A half-chance does arrive for Spain when Silva attempts an over-head kick inside the box, but his effort was always too high. Better from La Roja there.

Isco dances away from a couple of challenges before striking towards goal, but his effort was not even close to testing the Iran goalkeeper. Just a few signs that Spain are warming to their task.

Little over 10 minutes of the first period remaining, and Iran are still more than holding their own. That said, Querioz's side have not been out of their own half for some time now!

Iran finally break out of their own half as Rezaeian finds space in a wide position before delivering, but Ramos is on hand to head behind. Imagine the noise if Iran were to take the lead!

Iran might well be forced into a change here as their captain Hajsafi goes down, and he does not look comfortable. Indeed, there seems to be some movement on the Iran bench here.

Hajsafi is moving a little easier as he attempts to run off the injury.

Iran goalkeeper Beiranvand is rolling around following perceived contact from Diego Costa, but the referee is not taking any action. VAR? It is no surprise that the Atletico forward is involved!

Nothing in that for me, and it seems that no further action will be taken.

Alba has another cross cleared from the left as Iran continue to defend their lines here.

Costa volleys the ball straight out of play as Spain's frustration continues. Iran are just a few minutes away from completing their first task - getting through the first half at 0-0.

We are into the first of three additional minutes at the end of the first period.

CHANCE! Best chance of the half for Spain as Silva finds space inside the Iran box before striking towards goal, and his effort is deflected just wide of the Iran post.

So there we have it; the referee brings the first period to a close with the two teams level at 0-0. Spain have absolutely dominated the match in terms of possession, but clear chances have been few and far between. Carlos Queiroz has this Iran team so well-drilled in a defensive area!

STATISTICS! Spain incredibly had more than 80% of the possession in the first period, while they managed 10 attempts. That said, just one of those efforts was on the Iran goal. Iran, meanwhile, had two attempts off target in the first 45 minutes. No yellow cards to report thus far in Kazan.

BENCH WATCH! Interim Spain boss Hierro has a wealth of talent on his bench tonight, with the likes of Thiago, Asensio, Aspas, Rodrigo, Saul and Koke all capable of making a difference in the second 45 minutes. Iran, meanwhile, have options in the shape of Dejagah, Shojaei and Jahanbakhsh.

RESTART! Iran resume the action here...

... no changes from either side at the break, which is not too much of a surprise. However, I suspect that both managers will have alterations in mind as the second period develops here.

Alba breaks down the left before delivering low into the Iran box, but Hosseini is on hand to clear once again. Silva is then dispossessed inside the box as Spain boss the possession here.

CHANCES! Big chance for Spain as Busquets flicks a header towards Pique inside the Iran box, but the centre-back sees his effort cleared. Busquets then hits one from outside the box, and Iran's goalkeeper does well to push the ball behind under pressure!

CHANCE! Isco fires over the crossbar following smart work from Carvajal. Spain are finally starting to find some space, which was just not the case in the first period.

CLOSE! Oh my word! Iran thought that they had scored as the net rippled following a strike from Karim, but it was the side-netting! So close to the opening goal!

Spain make the breakthrough in the 54th minute as Costa turns inside the Iran box before Hosseini smashes the ball against the Atletico forward, and the ball drops into the corner!

It looked to be an own goal, but Costa will certainly claim that!

All happening at the moment as Isco delivers another deep free kick into the Iran box, and you do get the feeling that we will see more goals in the final 30 minutes of this football match.

WIDE! Taremi heads an Amiri cross just wide of the Spain post from close range!

Iran win a free kick in a forward area as Ramos brings Taremi to the ground...

... GOAL! Iran 1-1 Spain (Ezatolahi)

Iran appear to be level, or are they? VAR!

Ekatolahi smashed the ball home from close range, but was there an offside?!

GOAL DISALLOWED! No goal for Iran! Offside!

Iran are coming out to play; there is no question about that. Spain are having to defend, but that will leave space down the other end of the field. We have a proper game on our hands here.

Spain are preparing to introduce Koke for the final 20 minutes of this match.

Iran skipper Hajsafi is down receiving treatment once again.

IRAN SUB! Hajsafi is replaced by Mohammadi for Iran.

Spain look to bundle the ball over the Iran goal-line from close range, but the referee eventually blows for a free kick! Pique and Costa were in there, but Iran survive conceding a second.

SPAIN SUB! Koke replaces Iniesta for Spain.

You do get the feeling that there is another goal in this match as we head for the final 15 minutes of action. Iran have to come out, and that will leave space for Spain down the other end.

IRAN SUB! Jahanbakhsh replaces Karim for Iran.

CHANCE! Taremi comes close to meeting a deep cross inside the Spain box, but the attacker just cannot make contact! Huge moment for Iran there, but Spain stay 1-0 ahead.

Isco strikes a free kick into the Iran wall as the score stays 1-0 with 78 minutes on the clock.

BOOKING! Amiri (Iran) is booked for a poor challenge on Carvajal.

SPAIN SUB! Asensio replaces Vazquez for Spain.

Possession football from Spain as Iran are forced to come further out of their defensive shape. Still a good 10 minutes of football to play in this match, and the result is far from certain.

CHANCE! Incredible chance for Taremi as the number 17 rises highest inside the Spain box to meet a cross from the left, but he somehow plants the ball over the crossbar!

The noise has been deafening inside the stadium from the first whistle, and that remains the case. Iran have just passed up an incredible chance though, and they may not get another here.

IRAN SUB! Amiri is replaced by Ghoddos for Iran.

Wonderful football from Spain in a wide position as they keep the ball away from Iran. Some of Isco's football has been magical tonight, and La Roja are closing on a huge three points here.

SPAIN SUB! Rodrigo replaces Costa for Spain.

Pass, pass, pass from Spain as we head for stoppage time.

We are into the second of four additional minutes in Kazan.

De Gea claims a header from Azmoun as the clock ticks on here.

BOOKING! Ebrahimi (Iran) is booked for a foul on Asensio.

Iran break clear down the right following a poor pass from Isco, but the cover is back.

So there we have it. The referee brings the second period to a close with Costa's goal seeing Spain beat Iran. La Roja have joined Portugal on four points in Group B, while Iran sit third on three points ahead of the final matchday. Thanks for joining our live coverage once again!
