SUNDERLAND (England) - SUNDERLAND manager Roy Keane suggested that his 100th match in charge could be his last after seeing his team crushed 4-1 by Bolton in the Premier League on Saturday.

Djibril Cisse put Sunderland into an 11th-minute lead, but the team capitulated and defensive mistakes gave Bolton a route back into the game.

After slumping to a fifth loss in their last six matches, Keane's side fell to 18th in the 20-team standings.

'I ask myself every single day if I am the right man for Sunderland,' Keane said. 'I asked myself this morning and I said that I was. Tomorrow morning if the answer's no we will have to look at it.'

'I have to be honest in my assessment. It's not about what's best for Roy Keane. It's Sunderland Football Club. I might wake up on Monday morning and think I'm the right man. On Tuesday it might be different.'

Cisse's opener was quickly cancelled out by Matthew Taylor and by the 21st Gary Cahill had put Bolton ahead.

Johan Elmander compiled Keane's misery either side of the break after exploiting slack defending.

'I'm the manager of this football club and ultimately I'm responsible and I've never shied away from that,' Keane said.

'That's part of being a manager and that's why I take full responsibility for today and the run we're on and everything else.' -- AP
