Martin Keown believes Arsene Wenger must be earnestly considering his Arsenal future.

The Gunners were thrashed 5-1 by Bayern Munich in the Champions League on Wednesday night, prompting former defender Keown to question the Frenchman's tenure at the Emirates Stadium.

"I feel for Arsene Wenger, this is obviously his lowest point ever at Arsenal," he said on BT Sport.

"He must be seriously considering his future because that was embarrassing.

"I can't say I'd like to see him go when you have won things (with him). He's like a footballing father.

"But I'll be surprised if he is there next season because of the way things are going. It is spiralling down and down and down and out of control."
