Deniz Undav (On for Enciso 82’) N/A. Lobbed home Brighton’s second to kill-off Arsenal hopes on day and in the title race. Reuters
ARSENAL RATINGS: Aaron Ramsdale 5: Turned Enciso effort over bar in what was Brighton’s only effort on target in first half. No chance with first goal, lobbed for second after Trossard made a mess of the keeper’s pass out from back. Parried Udav’s shot straight to Estupinan for the third. Reuters
Ben White 4: Found both Enciso and Mitoma handfuls as the Brighton widemen switched flanks. Tormented by latter in run-up to Enciso’s goal and the Japanese winger had White on toast on more than one occasion. Reuters
Gabriel 7: Arsenal’s best defender, and probably best player, on day when many of his teammates struggled. Brazilian was solid from start to finish. PA
Jakub Kiwior 4: Up against a talented and physical opponent in Ferguson who held off the Pole’s challenge to shoot wide in first half. Went down holding leg just before Enciso scored and left Arsenal man down when he surely should have stayed on feet. Getty
Kieran Tierney 5: Back in team in place of Oleksandr Zinchenko, which many Arsenal fans felt should have happened well before the Ukrainian’s injury. But had a tough time against direct running of Enciso. Reuters
Jorginho 4: The fulcrum to Arsenal’s win at Newcastle last week, was left moaning at minor Brighton challenges this one as the visitors harried Arsenal’s midfield from start to finish. AFP
Granit Xhaka 5: Has been the heartbeat of Arsenal’s title challenge but lost battle in centre of park and both centre-midfielders were replaced midway through second half as Gunners chased game. AP
Martin Odegaard 6: Left dazed after taking ball full in face in first minute. Recovered to fire low strike from edge of box just wide after quarter-of-an-hour. Drilled a shot across face of goal and well wide in first-half stoppage time. Not one to remember in what has been superb season for Norwegian. EPA
Bukayo Saka 5: First sight of goal came just before half-time but he pulled shot wide of Steele’s near post. Like rest of Arsenal’s attackers, struggled to make impact. EPA
Gabriel Martinelli 5: Incredibly, not even shown yellow card for clattering into Mitoma that could easily have been red in first 10 minutes. Caicedo’s crunching tackle from behind – that should also have been at least a booking - soon after ended Brazilian’s match inside 20 minutes. Reuters
Gabriel Jesus 6: Had low strike from tight angle turned out for corner by Steele at his near post. Certainly cannot fault his workrate but Arsenal needed more threat in front of goal. AFP
SUBS: Leandro Trossard (On for Martinelli 18’) 6: Early introduction against former club and nearly opened scoring when he cut inside and clipped the Brighton bar on 30-minute mark. Hit weak shot straight at keeper in 71st minute. Awful touch led to Brighton’s second. PA
Reiss Nelson (On for Jorginho 60’) 6: Drilled shot centremetres wide not long after coming on. AP
Thomas Partey (On for Xhaka 60’) 5: Brought on to bolster midfield that had struggled to get foothold on game but failed miserably to change the script. Booked late on. Getty
Eddie Nketiah (On for Jesus 77’) N/A. Reuters
Emile Smith Rowe (On for Odegaard 77’) N/A. PA
BRIGHTON RATINGS: Jason Steele 7: Had away hearts in mouths trying to play ball out from back on several occasions. Blocked Jesus strike at near post with his foot that was Arsenal’s sole first-half shot on target. Surprisingly untroubled after break. EPA
Moises Caicedo 8: Playing at trick-back again due to injuries but was excellent away from his midfield comfort zone. Arsenal’s January transfer target should have been booked, at least, for revenge tackle on Martinelli who had clobbered Mitoma minutes earlier. Reuters
Levi Colwill 8: One clever ball over Arsenal defence in opening 45 minutes to Mitoma starting move that ended with Enciso stabbing good chance way over bar. Outstanding at the back alongside Dunk. Getty
Lewis Dunk 8: Crucial captain’s block on Arsenal attempt on goal on edge of half-time then came flying out to try and charge down Saka shot that was enough to put off the England man who shot wide. A typically committed performance from defender. Getty
Pervis Estupinan 8: Had game’s first booking for shove on Saka which was a far less serious challenge than either Martinelli’s or Caicedo’s that both received no card. Slightly fortuitous assist chopping cross into ground that looped straight to Enciso who scored. Good finish on rebound to make it 3-0. Getty
Pascal Gross 8: A key player in Brighton’s pressing game at the Emirates and made life difficult for Arsenal players in possession. A cool and clam performance from German. Harsh booking for foul on Jorginho. PA
Billy Gilmour 7: Former Chelsea man played his part in what an impressive Brighton performance and helped frustrate and nullify Arsenal’s midfield. AP
Alexis Mac Allister 7: Argentine, linked with move to Liverpool in UK media this weekend, almost put Brighton 2-0 up but fired shot just wide. Glides around the pitch and would be big surprising to see World Cup winner playing for Seagulls next season. Getty
Julio Enciso 8: Started on left and had game’s first shot on target when Ramsdale palmed his powerful strike over bar. Leant back and skied a decent chance later in half. Headed Brighton into the lead just after break. Caused chaos in Arsenal defence and ran himself into the ground. AFP
Karoru Mitoma 9: On receiving end of nasty shoulder challenge to the head by Martinelli in first half. Skinned White before setting up chance for Enciso later in half. Left same player for dead in run-up to Brighton’s goal and tormented White throughout. Getty
Evan Ferguson 7: Showed real strength to hold off Kiwior just before break but Irish attacker pulled shot wide of target. A real physical presence for Brighton who holds ball, has a nice touch and lets defenders know he’s about. Getty
SUBS: Danny Welbeck (On for Gilmour 60’) 6: Former Gunner was given warn reception by home fans after coming on. Drilled a shot couple of metres wide. PA
