Former Arsenal goalkeeper David Seaman has demanded that the club's current captain Granit Xhaka apologise following his outburst in Sunday's game against Crystal Palace.

The Swiss midfielder told Gunners fans to "f*** off" before storming down the tunnel after he was met with jeers, boos and foul language upon being substituted at the Emirates Stadium.

Speaking on talkSPORT, Seaman said: "There's no way you can do what he did, putting his hand to his ear and then swearing at the crowd.

"It's something as an Arsenal captain you just cannot do. You have just got to get on with it, get off, and deal with it afterwards.

"The other thing that surprised me is the fact Xhaka has not come out and apologised to the fans.

"I was captain at Arsenal for quite a few games and if something like that happened to me I would have been straight out in the press saying, 'I'm really sorry for my actions'."

While the former Borussia Monchengladbach midfielder is believed to have the support of his teammates, Xhaka is set to be left of Unai Emery's squad for Arsenal's game with Liverpool in the EFL Cup on Wednesday.
