Arsenal v Leeds United live: score, updates and line-ups

Full time: Arsenal 2-1 Leeds United. James Justin's fine finish had given Leeds a shock lead, but Arsenal responded in style - Calafiori bundling home from close range before substitute Bruno Guimarães, barely minutes into his cameo, curled in a brilliant winner. Saka went close to a third deep into stoppage time, forcing a save from Trafford, but it mattered little as Arsenal held on for a hard-fought win despite Leeds edging the shot count overall.

Deep into stoppage time and Arsenal are holding firm at 2-1. Ødegaard saw a close-range effort go wide before being booked and withdrawn for Merino, while Madueke had a shot blocked after being teed up by Saka as the Gunners keep probing for a third. Leeds haven't threatened further in this spell - just a late foul from Guimarães to concede a free kick - and with five added minutes nearly gone, Arsenal look set to see this one out.

Arsenal have seen out the last ten minutes without any further goals, holding their nerve at 2-1 since Guimarães' wonder strike. Saka almost added a third with a shot from outside the box that drifted just over, while Leeds' discipline continues to crack - another booking, this time for Justin before he was withdrawn. The stats are barely moving, with Leeds still edging the shot count, but Arsenal look the calmer side as they protect their lead.

Arsenal have turned this on its head! Bruno Guimarães, only on the pitch for seven minutes, curls a superb right-footed effort from outside the box to put the Gunners 2-1 up. A remarkable response from the bench after falling behind, and the Emirates is bouncing.

Arsenal are level! Calafiori pokes home from close range after Ben White's header back across goal, finishing off a move that began with Madueke's blocked effort. The Gunners have hit straight back from going behind and it's 1-1 at the Emirates.

Leeds strike again and this time it's deserved - James Justin curls a right-footed effort into the top left corner after Gudmundsson's cross, continuing their pattern of being the sharper side in the final third. Arsenal have had the ball but it's Leeds who lead on every attacking metric that matters, and now they have the lead to show for it too.

Quiet start to the second half so far, with the only real action a Stach header from Ampadu's knock-down that drifted wide of the target. Possession and the overall picture remain much as they were at the break - Arsenal dominating the ball at around 60% but Leeds still holding the edge in shots (7-4) and corners, so there's little to separate the sides as Arsenal look for a way to turn their control into chances.

Leeds have grown into this and briefly got on top, with Ampadu forcing a smart save from Raya with a header, while two late fouls from Tanaka and Ampadu earned them both yellow cards as Arsenal pushed for a breakthrough. Arsenal still lead the possession stakes at 58%, but Leeds have edged ahead on shots (5-3) and corners, making this a scrappier spell than the opening exchanges. Madueke's effort for Arsenal drifted wide, so it remains goalless heading towards half-time.

Arsenal have dominated the ball without quite finding a breakthrough, dominating possession at nearly 61% but struggling to turn that into clear openings against a well-organised Leeds. Havertz went closest, heading Madueke's cross straight at Trafford, while Lewis-Skelly's effort from range was blocked. Leeds have offered a threat on the counter though, with Stach testing the Arsenal defence with a blocked effort of his own, and they still edge the shot count 3-2.
