The German was furious with the Seagulls forward as he was carried off the pitch on a stretcher
Arsenal suffered yet another injury blow when goalkeeper Bernd Leno had to be carried off on a stretcher with what looked like a serious leg injury during the first half of Saturday's Premier League clash with Brighton, with the German appearing to blame Brighton striker Neal Maupay for the incident.
The 28-year-old screamed in agony when his right leg buckled underneath him after rushing out to claim a high ball on the edge of the penalty area.
His concerned team-mates quickly became aware of the seriousness of the injury and immediately called for the medical team to come onto the pitch.
After receiving extensive treatment, Leno was carried off the pitch on a stretcher but not before remonstrating with Maupay, who was in close proximity to the German as he competed for the high ball.
Replays showed Maupay had barged into Leno after the German had claimed the ball, which meant the Gunners number one was off-balance when he landed.
He was replaced by Emiliano Martinez for just his seventh Premier League appearance in nearly nine years at Emirates Stadium.
Leno, who joined Arsenal from Bayer Leverkusen in the summer of 2018, has been an ever-present in the Premier League this season, with his replacement Martinez restricted to FA Cup, EFL Cup and Europa League duty.
It is the second injury blow for Arsenal in as many matches after defender Pablo Mari suffered ankle ligament damage against Manchester City on Wednesday and was ruled out for the rest of the campaign.
