Martin O'Neill's has refused to rule himself out of the running to become the next Manchester United manager.
The Celtic boss has sparked more uncertainty surrounding the coveted Old Trafford post which is due to be vacated by Sir Alex Ferguson at the end of the season.
O'Neill has been linked with the job, but he has continually pledged his future to Celtic and expressed a willingness to extend his stay in Glasgow beyond his contract which expires in the summer of 2003.
But when asked if an approach from United would leave him an enormous decision to make, he replied: "Yes, well it hasn't happened so far!"
He also admitted that he would not 'regret' an approach and that admission is set to alert the United board and worry everyone inside Parkhead.
O'Neill said: "You would love to sit down and plan five years, but as a manager you can't do that.
"Alex Ferguson has eventually won the right to plan for the next five years if he so desires, but you can lose a few games and then you are yesterday's news.
"I wouldn't regret it if someone (United) offered you something and I assume then they might be pleased with the job that you're doing."
Celtic chairman Brian Quinn and his fellow directors have yet to put in motion contract talks with the former Leicester City chief.
He won the Treble in his first season in Scotland, but admitted he was not in too much of a rush to sit down this season.
"Nothing has happened yet," added O'Neill. "I'm quite sure that the board and the chairman will sit down at some stage to discuss things with me.
"I always think there's plenty of time to look at that and at the end of the season would be plenty of time.
"With the game being so fickle things can change very quickly, especially on the managerial front.
