Roy Keane has warned he may walk away from Sunderland Football Club if their supporters continue to hurl personal abuse towards his direction.

The Irishman came under-fire from Black Cats fans at the Stadium of Light following their less than convincing performance against Northampton Town, which left him less than impressed.

"I have no problems with fans expressing their opinions," said Keane. "But one or two had a go pretty much towards myself - and that's something I won't tolerate.

“That's something I've not come into the job to accept again. I appreciate criticism, constructive criticism, which I'm going to receive. Trust me, my biggest critic is myself.

"Yes, I got my team wrong, definitely. I should have gone with one or two younger players. But abuse like that is something I just won't tolerate. Listen, in football, everyone has short memories.

“There was some idiot about three or four weeks ago having a go and you remember these things. You shouldn't, because we've got some bloody brilliant supporters, but you always remember the idiots."
