Sunderland boss Roy Keane has warned he is ready to discard several players in a massive summer overhaul.

Keane renewed his calls for a massive transfer kitty to bring in new players after the defeat at Bolton and vowed to wield the axe in the coming days on members of his squad he feels have consistently failed to take their opportunities.

The Manchester United legend even went so far as to say he is fortunate not to have been shown the door himself.

"We've lost 22 games this season and people keep telling me we've had a good season - but I'm lucky to still be in a job," said Keane.

"You learn a hell of a lot about your players all the time and the Bolton match just confirmed what I'm thinking anyway. People say to me that we achieved our goal last week, but do we keep living in last week?

"Every game is an opportunity to impress me, but there will be changes in the summer because I'm saying the same thing week in, week out. I'm fed up of saying it and really bored with myself now at this stage - really, really bored."
