SUNDERLAND MANAGER Roy Keane launched a withering attack on his side after their 2-0 surrender at Bolton on Saturday and warned he is ready to discard several players in a massive summer overhaul.

"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 this match just confirmed what I'm thinking anyway.

"People say to me 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 at this stage - really, really bored."

Keane will throw out the players he feels are not up to the job after a superb strike from El-Hadji Diouf and an own-goal from Daryl Murphy handed Bolton victory.

Keane continued: "Gordon Strachan and one or two other managers have said if you tell a player something more than two or three times and he doesn't do it, then get shot of him. I've been very patient and very kind to some players. But we need to invest and we need to invest wisely. We need to move certain people on. That will be done this week - if not this week then the following week."
