Ferdinand - one of England's most impressive players at the World Cup - submitted a transfer request on Wednesday, which was promptly rejected by Ridsdale.

And Ridsdale attempted to persuade Ferdinand to commit his future to Leeds at a meeting on Thursday.

"I met Rio Ferdinand on Thursday and we had amicable and constructive talks about his future," said Ridsdale.

"I stressed that we do not wish to sell Rio under any circumstances and would like to see him fulfil the contract he signed in November 2000."

The Leeds chairman also emphasised that the club have not received a suitable offer for Ferdinand and added: "Rio has assured us that if the position remains as it is, he will give his full commitment as a player and captain to Leeds United."

Ridsdale also hinted that he wants the situation resolved by the time Leeds fly off to the Far East for their pre-season tour on Saturday.

"I hope I can soon go back on holiday to rejoin my family in Monaco, depending how the next 24 hours turns out," said Ridsdale.

But he did not mention whether Ferdinand had withdrawn his transfer request.

And Manchester United are understood to be poised to reopen negotiations should cash-strapped Leeds be left with no option but to sell their most valuable asset.

Leeds received an offer from Old Trafford for Ferdinand several weeks ago, which is believed to have been in the region of �20m.

The Yorkshire are likely to want at least �30m to prise Ferdinand away from Elland Road.
