Celtic are confident Martin O'Neill will remain as manager at Parkhead despite speculation linking him with a move to the Premiership.
The Ulsterman is believed to be top of Leeds United's list to replace sacked boss David O'Leary and reports suggest the Elland Road club could make an approach for O'Neill today.
But Celtic chairman Brian Quinn claims no contact has been made between the two clubs and insists any approach for the man who has won two league championships since his arrival in the east end of Glasgow two years ago will not be welcome.
Quinn told the Scottish Sun: "There has been a lot of speculation. I have not spoken to Martin.
"There has been no approach to us - and we certainly wouldn't welcome one.
"There's no need to do anything about Martin's position because nothing has happened."
When quizzed on whether steps had been taken to improve O'Neill's current contract at Celtic, Quinn said: "If the need arises we will. But there's nothing to do just now."
Quinn added: "Of course I am concerned. But Martin has always honoured his contracts in the past.
"He is an honourable man - so I think there's nothing to speak about."
