Celtic goalkeeper Artur Boruc has revealed he wants to quit Parkhead next summer.
The Poland number one has told journalists in his homeland that he is monitoring the Andy Webster case to see whether he can leave Glasgow a year before his contract expires.
Boruc is tied to the club until summer 2009 and both parties have the option of a one-year extension.
But Webster, now on loan at Rangers from Wigan, left Hearts a year before his contract expired after becoming the first player to use Article 17 of FIFA's transfer regulations.
Boruc, quoted in The Herald, said: 'I have decided I am going to leave Celtic in the summer.
'Celtic want more than £10million for me but I think it is too much.
'There is much to look forward to with the Champions League in spring and then the European Championship in the summer, but many things can change and I have to see what is best for me.'
FIFA ruled Webster had breached his contract without just cause and ordered him to pay £625,000 to Hearts, a fee Wigan had promised to pay.
But Hearts appealed, claiming they should receive more than £4million, and all parties are awaiting a ruling from the Court of Arbitration for Sport.
Boruc is out of action at the moment after undergoing minor knee surgery but he aims to return for the Old Firm derby on January 2.
'The operation went very well and I should be back next month,' the 27-year-old said.
'I cannot say for certain that I will be back for the game against Rangers but I will try really hard to be back in time because I enjoy playing in these games.'
