Southgate’s men have averaged 3.8 goals per game and are among the favourites for Euro 2020 on the back of runs to the semi-finals of the 2018 World Cup and this year’s Nations League.

“I mean, I would say that we’re definitely further ahead than we were heading into Russia,” manager Southgate said. “But we made massive strides in this period when we went into Russia.

“So, we’ve got to make sure that to get the level of performance next summer, we’re going to have to improve in the way that we did over that spell as well.

“And I think the team have belief, for sure, you can see the confidence.

“I said last night, they don’t come into these matches worrying about what might go wrong, they’ve got the confidence to control games with possession, and they know they’re going to score goals.

“So, yes, what we don’t know, because we haven’t had those tests more recently against the top eight or 10, is exactly how we’re going to cope in those moments.

“And to win the European Championship is, at the moment, no easier than the World Cup.

“The final four were all European, and you’ve got to add Spain, Germany, Portugal and all the others into that, so it’s a really high-level tournament.”

England certainly have the attacking ability to hurt any team at next summer’s finals, where Southgate’s side will play all of their group games at Wembley before hoping to return there for the semis and final.

Issues like set-piece frailties and their uneven midfield dynamic need to be worked on before then given Sunday’s display in Kosovo, where the scoreline flattered the visitors.

Kane, Rashford and Mount’s goals all came from the 79th minute at Stadiumi Fadil Vokrri, where the hosts gave England a touching welcome following the United Kingdom’s role in helping Kosovo during their time of need two decades ago.

“It was a difficult game,” Southgate said.

“It was an amazing reception from everybody from Kosovo which was, obviously, a special night for them and it was a privilege to be part of it so we thank them for that.

“I think similar to some of the games we’ve had where the teams have pressed us high – at first, it was not easy to play through their pressure but I thought (Harry) Maguire and Winks, in particular, gave us a real calmness on the ball to solve that problem.

“Not an easy pitch, you know, a lot of the guys were slipping around. To have control of the game that we did was good and then as the game went on, a bit more space started to open up and then our counter-attacking and forward play came into its own.

“I thought it was a really good test for us, we needed that. I was keen to see – I was quite happy at 1-0, at 65’, 70’, I was quite happy for that to go 80’, 85’, to see how we would cope with it because we need those sorts of games.

“It was a good test for the young players and the new players coming in, as well as some of the more experienced ones.”

After the game, Kosovo boss Bernard Challandes said he considered England favourites for Euro 2020 following this latest goalfest.

“I cannot say we have had no discipline,” he said.

“OK, at the end of the game we have made mistakes and we can’t make such mistakes against an opponent as England.

“But it was also perhaps a little because some players were very, very tired at the end of the game and as a side, we must say that England are so good. So good and the efficiency. We have paid.”
