Republic of Ireland boss Martin O'Neill is confident assistant Roy Keane would be a good fit for Celtic if they turned to him in their search for a new manager.
Some bookmakers have suspended betting on the former Manchester United and Ireland skipper, who had a brief spell at Parkhead as his playing career drew to a close, replacing Ronny Deila at the helm next season.
Keane, 44, has served as O'Neill's No. 2 since November 2013 and spoke to the Bhoys two summers ago about the vacancy to which Deila was eventually appointed, while O'Neill, himself a hugely-successful former Celtic boss, is confident he could do the job.
Speaking as he announced a 35-man squad for Ireland's pre-Euro 2016 finals friendly against Netherlands on May 27 at a news conference in Dublin on Thursday, he said: "I think Celtic is one of the great clubs in the world and I have to say that he was one of the great players in the world, so that's not a bad fit for a start.
"Could he do the job? I would have no problems with that whatsoever. Would he be capable of doing that? Absolutely. But as Roy said, you still have to be asked and so far, I'm not so sure that that's been the case.
"But I don't think that he would give things up here lightly. Something would have to, as he often says, his favourite phrase, rock his boat -- I think is what he says.
"But he has enjoyed it here. I think it has been good for him, but is he ready to go? Yes, he could very well be.''
