In the meantime, City were looking to cement second place in the Premier League, and a win against the Baggies would certainly help.
Albion have already essentially finished for the season, with neither Europe or relegation possible, but, having already set a new record for their best-ever Premier League campaign, they were be keen to finish on a high note.
In a game of many chances, it was City who netted the only goal of the game in the first half.
Read how the match played out in our live commentary below.
Roberto Mancini's men take to the side for the final time before they will take to Wembley for the FA Cup final at the weekend; a piece of silverware they are desperate to win. And with that, the players will certainly looking to impress the gaffer enough and force him to hand them a berth in the competition's conclusion.
Despite being title challengers for most of the year, City can still mathematically finish outside the top two, so they will be eager to cement their place as runners-up this season.
So, Pablo Zabaleta, Vincent Kompany, Matija Nastasic, Gael Clichy, Yaya Toure, Gareth Barry, David Silva and Sergio Aguero are all missing from the starting XI that drew with Swansea at the weekend.
And replacing those absentees are Micah Richards, Kolo Toure, Joleon Lescott, Aleksandar Kolarov, Javi Garcia, Jack Rodwell, Carlos Tevez and Edin Dzeko.
So a lot of attacking talent is sat on the sidelines tonight, so should the game turn a bit stale, don't be surprised to see the likes of Silva, Aguero, Long or Odemwingie enter the fray.
Roberto Mancini: "I am not satisfied as I wanted to win the Premier League, but now we cannot do anything about that, we cannot change it.
"But in the end we we are in the cup final and we are in second position, so we can be satisfied. But when you start the season you want to win [the league]."
One of the dangermen on display tonight, is Belgian hot shot Romelu Lukaku. The man, on loan from Chelsea, prompted international teammmate, and opponent tonight, Vincent Kompany to speak highly on him.
Kompany: "Romelu is probably one of the biggest talents in Europe at the moment. We are very lucky with him, being a very young striker and Christian Benteke.
"We have two unbelievable talents coming through. I am looking forward to playing against him. He will be a world beater in England very soon."
CHANCE! The first chance of the game falls to Albion, and with Lukaku. He is slid in with a lovely ball that he picks up on the edge of the box on the left. He shrugs off his marker before firing across goal, with Hart forced to save with his legs.
CHANCE! Another opportunity to West Brom, and another chance for Lukaku. The ball is played into him in the centre of the City half, and he has so much time and space he can just turn towards the left of the box. His touch is a bit heavy, but he smashes a low effort across Hart and just past the far post. West Brom and the Belgian are certainly enjoying themselves in the early stages.
CHANCE! Guess who? You got it. Lukaku gets a free header at the far post after City failed to clear away a Brunt freekick. Morrison clips the second ball in from the left, and Lukaku on the penalty spot rises to meet it. However, he can't get enough power on it, and Hart can catch comfortably.
CHANCE! Albion have yet another opportunity, this time with Markus Rosenberg. He has an effort at goal from just outside the box which goes wide of the left-hand post.
It's almost a complete role reversal of how you would have predicted this match to start. Albion, with not too much to play for, have been brilliant. City, with a cup final just around the corner, have been terrible so far.
Tevez goes for goal from the edge of the box with his left, but his shot is deflected out for a corner. Nasri whips it in but it's a routine catch for Myhill.
CHANCE! Myhill nearly gifts City an opener. He comes to catch the kick but isn't strong enough when up against Richards. The ball falls to Rodwell but he can only scoop it over the bar. City starting to grow into the match.
Tamas is receiving treatment at the moment. His face is literally red and dripping with blood after his head meets the high, but not malicious, boot of Kolarov. To be fair to the City man, Tamas ducked into the challenge bravely, but I'm sure as anything that he regrets it now.
BOOKING! As Tamas temporarily makes his way off the field with a towel over his head, Phil Dowd shows Kolarov a yellow card. Not surprising. Not entirely his fault but you can't put your studs up that high.
CHANCE! Tevez comes fractions away from banging this one in the top corner. City have a nice spell of passing play which finds the Argentine in the centre of the edge of the box. He spreads the ball on the right to Milner, who then gives it back. Tevez, unmarked, curls an effort first time, but the ball just rises over the crossbar. Close.
West Brom have a couple of chances from a corner, with Mulumbu smashing one from the edge of the box on the volley, but City can block and clear the danger.
CHANCE!...of sorts for Albion. The Baggies hit City on the break, with Lukaku threading through Rosenborg on the right side of the penalty area. He manages to get his shot away, but with no power. About five minutes later, it seemed, Hart bent down to pick up the ball.
CHANCE! This one was a chance, but this time for City. Nasri leaves Morrison for dead on the left of the box and chips a high cross to the edge of the six-yard box. Dzeko rises and flicks to a shadowing Milner, who brings the ball down but then balloons it over the bar under pressure. Real opportunity there.
OFF THE BAR! City have two chances in the space of a minute. First, Rodwell just needed to get a head to a Kolarov cross to put City ahead, but he ducked out of it. Moments later the ball then fell to Tevez, who opens up his body on the left, and cracks a shot that bounces off the crossbar. A brilliant effort, but no goal yet.
And on that note...City take the lead. Mulumbu tries to be too clever in the middle of the park and loses possession. Tevez is fed in down the right, and drives towards the byeline. He whips in a cross to the edge of the box where Dzeko, guides a volley into the far corner with the inside of his boot. A class goal. Dzeko bites the Baggies once more.
CHANCE! Same combination for City. Tevez holds the ball at the byeline, and has time to chip the ball up and clip a cross into the box. Dzeko meets it in the middle with a volley, but this one is deflected over for a corner.
CHANCES! City have two bites of the cherry, first with Milner who twists and turns before hitting a cross-come-shot which forces Myhill to palm the ball away. Rodwell then drives a hard half-volley towards goal, but it's blocked. Half-hearted appeals for a penalty is the result.
OFF THE POST! City rattle the goal frame yet again, this time with Milner. Lovely flowing football from City ends up at the feet of Milner, who blasts a low effort from 30 yards out, but it smacks off the outside of the post. Close shave for Albion.
CHANCE! Albion have their first chance in a while, and it's hit by Morrison. He does so well to pluck the ball out of the sky and smash a shot towards goal. Unfortunately for him, it goes straight to Joe Hart. Good technique though.
SAVE! Lukaku is given half a chance to have a sniff on goal, but he outpaces and overpowers Richards to the ball, he gets there first but Hart is out quickly and bravely to snatch the ball.
However, City grew into the half, and finished the stronger of the two. They could be 3-0 up to be honest with you, but they will settle for the one-goal lead after a dodgy start. It was a great goal from Dzeko as well, with Tevez playing a big role in it.
Lukaku dribbles forward to the edge of the City box, he should shoot, but instead opts to play in Rosenberg. His pass his poor and goes out for a goal kick.
OFF THE BAR! Well, that was a surprise. Rosenberg, who has done nothing so far, absolutely thunders the set piece against the crossbar. Hart was well beaten for the first attempt but does terrifically well to recover and palm away Jones' follow-up header. Albion were so close there!
Not too much going on at the moment. Teves is playing very well though. Stayed on his feet as he evaded the challenges, and came close to picking out a killer pass towards Dzeko.
CHANCE! Morrison goes close for Albion. He shimmies away from Garcia to open up the space to shot. His low shot troubles Hart, who if forced to dive and get a fingertip to the ball. Corner.
Not much in the way of chances, but West Brom are really coming back into this game. City are struggling to deal with Lukaku's strength. As I say that, he wins the corner after his header was deflected out of play.
CHANCES! All for City. Brilliant stuff from Nasri, who somehow manages to create a beautiful cross which flies towards the far post from the byeline. The ball falls to Rodwell who blasts the ball at Myhill. Tevez is just beaten to the ball as Albion clear away, but it is quickly back to the far post, where Rodwell takes a touch and cannons the ball towards goal. Another good block from Albion, and they escape.
HANDBAGS! Samir Nasri doesn't take kindly to being bumped over by Yacob. Both players go head to head, and come away with yellow cards. No malice in the challenge at all.
CHANCE! Lethargic stuff from City, as Mulumbu causes trouble on the right of the area. He cuts the ball back for Billy Jones, who tries a shot a goal, but City get a good block to it and clear.
CHANCE! Long is thrown straight into the action. A lovely knock-down by Lukaku is met by a bursting Long, but he slams a low effort into the sidenetting at the near post.
City are looking for that killer second goal. Tevez and Dzeko both go close to finding it, but Albion can clear away. The Baggies still have a chance here.
CHANCE! Maicon bursts down the right once more, but picks out Barry. The England internationals shot is slotted towards the corner, but is too slow to beat Myhill.
West Brom were great in parts, City were superb in patterns. But ultimately, the hosts were too strong for the visitors, in a match that should have finished with a lot more goals.
