The message was published following the Gunners' disappointing 2-2 draw with Crystal Palace.
Arsenal raced into a 2-0 lead early on but threw away their advantage , and centre-midfielder Granit Xhaka angered fans by gesticulating at them when he was substituted after 61 minutes and allegedly telling them to "f*** off" as he was booed by the Emirates faithful while he made his way to the tunnel.
After the match well-known Arsenal supporter Troopz, who regularly appears on Arsenal Fan TV, posted an angry message on his social media which was 'liked' by Lacazette, suggesting the Frenchman shares the same opinions as the Gunners fan.
Troopz said: "Im 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 but bro, enough is enough. Xhaka can f*ck himself as well. Never wanna see him in an arsenal top again! #AFC #EmiratesStadium #TimesUp".
