Celtic manager Martin O'Neill has pledged his short-term future to Celtic and ruled out any possible move to Leeds United.

"There has been no approach from Leeds and I want to see through the remaining year of my contract," O'Neill told a Dublin audience at an after-lunch speech.

Celtic are currently in the Irish capital preparing for the new season and O'Neill broke his recent silence about the Leeds speculation at a function attended by local businessmen.

"I was shocked when I heard that David O'Leary had been sacked but these things happen in football," he said.

"There are only a few managers in football who are unsackable, like Brian Clough, Arsene Wenger and Sir Alex Ferguson - and I am not one of them.

"I know that I can be sacked at any time, but if Celtic do not sack me I intend to see out my contract."

O'Neill was believed to be top of Leeds' list of candidates for the vacant managerial post, but it appears the Elland Road club must now look elsewhere.

Earlier on Friday Celtic warned the Yorkshire side they would fight to keep hold of O'Neill.

A Celtic spokesman said: "It is safe to say if Leeds or any team approached us, the club would do everything in its power to keep Martin at Celtic."
