The pace of the game is electric now, it's end-to-end as Brighton first have a chance after Fernandinho fouls Duffy and the Seagulls get another opportunity from a set piece. City defend well and break up the other end, with Sterling ending the attack with a shot at goal, which is well saved by Ryan.
90'
There will be a minimum of three minutes added time played.
89'
Knockaert appeals for a penalty after going down in the box under pressure from Laporte. However, there isn't anything in that and in any case it looked like Knockaert handled the ball in the first place to control the ball.
88'
Just a couple of minutes left to play now and the game still could go either way, with Brighton really trying to throw everything at City. A nervy ending for both sets of supporters.
86'
Good effort! Izquierdo tries to curl the ball into the top corner from the edge of the box, but it's not close enough to the corner and Ederson makes a comfortable save.
84'
Quality play by City, playing the ball out from the back very well despite being under a lot of pressure from the Brighton forwards.
82'
J. Locadia enters the game and replaces Y. Bissouma.
Brighton make their third and final substitution, with Bissouma coming off and he's replaced by Locadia.
81'
Knockaert wins a corner for Brighton and urges the Seagulls supporters to stand up and get behind the team. They've been terrific today, never given up on their side getting back into the game. Unfortunately the corner is poor and City comfortably clear.
79'
J. Stones enters the game and replaces B. Mendy.
City make a substitution just before the corner, with Mendy coming off and he has been replaced by Stones. A sign perhaps that Guardiola is trying to see the game out now.
Good block! Dunk throws himself towards the ball as Sterling fires a shot at goal, which looked to be heading on target. However, the centre-back diverted the ball out of play for a corner.
Minute
Description
78'
Wicked ball into the box by Mendy, which Dunk has to flick out of play for a corner. Gundogan whips the set piece into the box, but the Seagulls defend it well.
74'
Still all to play for here, City don't look as assured as they did in the first half and are now trying to slow the pace of the game down and see the game out.
72'
L. Dunk gets yellow.
The Brighton skipper Dunk is shown a yellow card after a late challenge on Bernardo Silva, he doesn't get anywhere near the ball.
70'
J. Izquierdo enters the game and replaces A. Jahanbakhsh.
Another change now for Brighton, with Jahanbakhsh coming off and he is replaced by Izquierdo.
68'
This game could still go either way as victory isn't yet secured by City, they're pushing forward now after having to withstand a lot of Brighton pressure. Sterling looks very lively, but Jesus is one player who has hardly been involved in the second half so far.
66'
F. Andone enters the game and replaces G. Murray.
Brighton also make a change and it's an attacking one, with Murray the man coming off and he has been replaced by Andone.
65'
Fernandinho enters the game and replaces K. De Bruyne.
Manchester City make their second substitution of the game, with De Bruyne making way for Fernandinho.
64'
SAVE! Terrific effort by Sterling from the edge of the box and Ryan produces a fine save to tip it out wide, the first real save that the Brighton keeper has had to make.
61'
Decent effort! Gundogan with a shot on the volley from the edge of the box, but it's straight at Ryan, who comfortably gathers.
60'
Another Brighton free-kick that they bring everyone forward for, with Duffy and Dunk causing a lot of problems in these positions. Knockaert again with the delivery, but it's not good enough and City clear.
58'
City have started to get on the ball more now and slow the pace of the game down, but they aren't troubling the Brighton defence.
56'
The game is starting to become more stretched now as Brighton start to pile players forward in search of a goal, but it's leaving more space at the back for City to exploit. Great opening to the second half.
53'
This is a really good spell by Brighton, another free-kick opportunity which causes more problems and they now have a corner.
51'
Free-kick in a really good position for Brighton and their supporters are urging their team forward and hoping to see something come of this set piece. However, Knockaert's ball into the box is poor and easily headed away to safety. Wasted opportunity.
50'
Danilo gets yellow.
This is much better from Brighton in the opening five minutes of the second half, they are playing with much more pace and are putting their opponents under more pressure and not allowing them as much time on the ball.
Danilo is booked after he brings Jahanbakhsh to the ground down the left wing, a late challenge by the half-time substitute.
46'
Danilo enters the game and replaces K. Walker.
City have made a substitution ahead of the second half, with Walker coming off and he has been replaced by Danilo.
The second half is underway!
45' +2
HALF-TIME: MANCHESTER CITY 1-0 BRIGHTON
45'
There will be a minimum of two minutes added time played.
44'
Terrific tackle by Bernardo to block a cross into the box by Bernardo Silva, who looked to have beaten the Brighton left-back. This corner causes more problems, with a bit of a goalmouth scramble in the six-yard box, but the Seagulls eventually clear the ball.
42'
Another City corner, which De Bruyne whips into the box towards Laporte, but he drags his marker to the ground and the referee awards a free-kick to Brighton.
38'
There's not long left on the clock before the half-time whistle now, can City double their lead before the break? Or, will Brighton be able to find a way back into the game?
36'
The pace of the game has dropped slightly, apart from a couple of decent passages of play in the opening few minutes and the City goal. They haven't created much else in the final third, with Brighton defending well.
32'
A. Jahanbakhsh gets yellow.
K. Walker gets yellow.
A bit of a coming together between Walker and Jahanbakhsh deep inside the City half, as Walker sees the ball out of play and Jahanbakhsh comes in a little bit late on the right-back. The pair square up to eachother and Walker appears to move his forehead towards Jahanbakhsh, almost a headbutt, but VAR check it and a red card isn't shown.
Jahanbakhsh is also booked. The two players are still having words with eachother, they both just need to calm down.
Walker is just shown a yellow card for his coming together with Jahanbakhsh. Some would argue that he's lucky to be on the pitch after that.
31'
Deep Brighton free-kick into the City penalty area, with Dunk and Duffy both going up for it. Duffy gets his head to the ball, but his header goes well wide and doesn't trouble Ederson.
29'
De Bruyne steps up to take the free-kick and he opts to cross into the penalty area, but it's well headed away by Brighton.
28'
There is a good tempo to the game, it's been an entertaining game so far. Free-kick to City in a very good position, after Stephens bring David Silva down around 25 yards out. A decent position for a shot at goal.
26'
Better from Brighton, they've manage to keep the ball in the City half and make their opponents do some defending. Walker is back on the pitch, it looks like he is going to try and run the injury off.
20'
Decent effort! It comes from a long kick forward by the goalkeeper and the ball breaks nicely for Propper on the edge of the penalty area, but he drags his low shot wide of Ederson's goal.
18'
Brighton have a corner! Their best passage of play so far and it ends in a set piece, which Knockaert whips into the box, it falls to Dunk at the far post. However, the centre-back fires his cross back into the six-yard box high over the crossbar.
16'
The Brighton supporters certainly haven't let the City goal dampen their spirits, they have come to Wembley in huge numbers and outnumber their opponents in that sense. It's a cracking atmosphere here.
14'
Brighton just can't keep hold of the ball right now, Murray is very isolated up top and the Seagulls haven't yet broken into the City final third and looked like testing Ederson.
12'
The Seagulls have everyone back inside their own half defending, with City playing the ball comfortably around the pitch at the moment. When Brighton do get on the ball they are giving it away far too easily, with Murray unable to hold the ball up for his teammates.
8'
Knockaert is given a warning by the referee after he throws himself to the ground and appeals for a foul after breaking forward on the counter. It looks like he hasn't been booked due to how early on in the game we are.
6'
Brighton just need to settle the game down now, get on the ball and string a few passes together after a hectic opening period and they've had to do a lot of defending.
4'
Gabriel Jesus has scored a goal for Manchester City! Assist by K. De Bruyne.
It's all City in the opening few minutes, with De Bruyne and Sterling already getting on the ball in the final third and Brighton are having to sit deep and defend in numbers.
It's an inch perfect cross from De Bruyne and Jesus was unmarked at the far post to head the ball home from the edge of the six-yard box.
GOOOAAALLL! It's taken just four minutes for Manchester City to take the lead, it's 1-0! Jesus the man on the scoresheet, finishing off a fine move. Laporte plays a glorious pass out wide, it get laid back to De Bruyne who whips a superb cross into the box, perfect for Jesus to run onto and head the ball into the bottom corner. He simply couldn't miss from there.
2'
City go on the attack early on, winning the ball off Brighton straight away and De Bruyne wins a corner. However, Brighton defend the corner well and manage to clear the danger.

We're underway!
Hello and welcome to our LIVE match commentary of the FA Cup clash between Manchester City and Brighton at Wembley.
The two sides met earlier in the Premier League season, with City securing a 2-0 victory at the Etihad. However, the two teams won't meet again until the final day of the season, a game that could be vital for both sides at opposite ends of the table, as it looks like the title race will go down the wire. Meanwhile Brighton are only five points above the final relegation spot.
This is only a second FA Cup semi-final for Brighton, who were quarter-finalists last season. They last played at Wembley back in 1983 when they lost the final against Manchester United. The Seagulls have lost their last two Premier League games, suffering defeats against Southampton and Chelsea.
Manchester City are still on for the quadruple this season, having already lifted the EFLCup at Wembley earlier this season. They last lifted this trophy back in 2011, when they beat Stoke City in the final. However, they did make it to the final again two years later, but suffered a 1-0 defeat against Wigan Athletic. They come into today's game on the back of a 2-0 victory over Cardiff City on Wednesday.
MAN CITY SUBS: Arijanet Muric, Danilo, John Stones, Fernandinho, Leroy Sane, Riyad Mahrez, Phil Foden.
MAN CITY (4-3-3): Ederson; Kyle Walker, Aymeric Laporte, Nicolas Otamendi, Benjamin Mendy; Ilkay Gundogan, David Silva, Kevin De Bruyne; Bernardo Silva, Gabriel Jesus, Raheem Sterling.
BRIGHTON (4-4-1-1): Mat Ryan; Martin Montoya, Shane Duffy, Lewis Dunk, Bernardo; Anthony Knockaert, Dale Stephens, Davy Propper, Alireza Jahanbakhsh; Yves Bissouma; Glenn Murray.
BRIGHTON SUBS: David Button, Bruno, Gaetan Bong, Dan Burn, Jurgen Locadia, Florin Andone, Jose Izquierdo.
The teams are out at Wembley and kick-off is just a few minutes away, stay tuned for all of the match action!
A lot of possession for City, but only one shot on target which was the goal. Meanwhile Brighton have had a couple of decent chances, but not yet forced Ederson into making a save. Brighton still have a chance in the game, but City have been very dominant so far.
That's all from us today folks, we hope you enjoyed the game!
Not the best performance by City today and they'll have to play much better against Tottenham in the Champions League quarter-final on Tuesday. Brighton will now turn their attentions back to securing Premier League survival, they face Bournemouth next Saturday.
