Sunderland boss Roy Keane has warned fans he won't "tolerate" abuse after copping an earful during their scratchy Carling Cup victory over Northampton.

Keane said: "Abuse may be part of football but I won't tolerate it.

"I appreciate constructive criticism, which I'm going to receive, and trust me, my biggest critic is myself.

"In football, everyone has short memories. We've got some bloody brilliant supporters but you always remember the idiots.

"Some people were targeting me. I'm not going to go into it but that's something I've not come into the job to accept."
