Former Arsenal midfielder Emmanuel Petit has slammed Granit Xhaka after he appeared to swear at supporters in the Gunners' 2-2 draw with Crystal Palace on Sunday.
The Swiss international reacted to jeers from the Emirates Stadium crowd when he was substituted, prompting further boos in response:
Petit, who won the Premier League title and the FA Cup with Arsenal in 1998, told Paddy Power:
"For me, he can't be the Arsenal captain any longer. It's impossible. What he did was unacceptable.
"What he did on the pitch is one thing, I've made it clear that I don't know what he adds to the team.
