Newcastle United boss Sam Allardyce has backed Sunderland rival Roy Keane's slag a WAG row.

Allardyce said: "There is no European football here first and foremost, and it's a case of 'not a big enough city' on some occasions.

"When you find that it might be a problem because the situation doesn't suit the wife, then I agree with Roy.

"If you are a professional footballer, you are doing what you love doing. You are at the top of the tree in your field.

"For you to then not go to a particular football club for non- football reasons is something that is hard for us old boys to cope with.

"It's a difficult one to get your head around, but it's a fact of life now. Like Roy, I don't agree with it, but you have to deal with it sadly."
