Tottenham manager Harry Redknapp still hopes to keep Luka Modric amid reports that the Chelsea target has submitted a written transfer request.
Modric is desperate to move to Stamford Bridge, but Spurs are determined to hold on to their man and have rejected bids of £22million and £27million.
Media reports claim the 25-year-old has put in a transfer request before jetting out for a pre-season tour of South Africa to try to force through a move.
But Redknapp insists any such tactic would have no impact on the club and chairman Daniel Levy's stance that a player who has five years left on his contract is not for sale.
Redknapp said: "We know he wants to leave and whether he writes it down on a piece of paper doesn't really make any difference to our stance.
"He's a great player and we don't want to lose him."
Modric, who could potentially earn £120,000-a-week at Chelsea, has already claimed that Levy has betrayed a gentleman's agreement which was struck when he signed a new six-year contract in May 2010.
Levy insists no such agreement exists, but Modric believes there was an understanding that Tottenham would listen to offers from perceivably bigger clubs.
Speculation has suggested that Lyon's £9m-rated Bosnian, Miralem Pjanic, is being considered by Tottenham as a potential replacement.
