ALEXANDRE LACAZETTE could come under fire from his manager after appearing to like a post on social media slamming Unai Emery and Granit Xhaka.
He also cupped his ears and took off his shirt before bolting down the tunnel.
Boss Emery is also in the firing line from supporters following yet another frustrating performance at the Emirates.
Fans watched their side blow a two-goal lead to leave them four points adrift of Chelsea in fourth and pile more pressure on the Spaniard.
It was all too much for one fan who took to social media to share his frustrations at the pair.
Alongside a picture of him inside the Emirates sticking his middle fingers at the camera, he wrote: "I'm sorry, I'm done with this now.
"You can't be 2-0 up at home to Palace and draw. Emery I've backed you bro, enough is enough.
"Xhaka can f*** himself as well. Never wanna see him in an Arsenal shirt again!!"
It proved a hugely popular post with fans but also gained the attention of Lacazette who controversially liked it.
The Frenchman has yet to comment on his actions but it could prove that all is not well inside the dressing room at the moment.
Meanwhile Xhaka could be punished by the club by being stripped of his captaincy.
Emery said: "We are going to speak with him. In one moment he was very hot. His reaction was wrong.
“Xhaka was wrong. Now we need to stay calm and speak to him inside the club about that reaction.
“We are here because we have supporters. We play for them and need to respect them, whether they applaud or criticise.

“Now is not the time to speak about the captaincy but we are working with every player to manage dealing with the pressure.
“We can play with our hearts and sometimes get hot in difficult moments but must always be clever.
“I’ve had similar in the past but this evening the connection between team and fans was amazing.
“There was one small individual incident but they support us and we must respect them.”
