Want-away striker Louis Saha has told Fulham he will leave for nothing at the end of his contract if he is not allowed to join Manchester United now.
United have had two bids rejected for the Frenchman and he is angry they may let him go in the summer instead.
"The club say they would rather sell me in six months' time but I am fed up now," said Saha.
"Either I leave now or I am staying at Fulham until the end of my contract which finishes in 2006.
"If Fulham love me that much they are going to have to cope with me until the end and then I will leave them for zero euros.
"They have not been honest. The club's managers keep changing their opinion.
"One day they say yes to a transfer and the next day they say no. They think I am an object.
"I however feel that the road which leads to Old Trafford is about to open," Saha told French newspaper Le Parisien.
Reports on Thursday suggested Chelsea were about to enter the bidding for the 25-year-old, but Fulham rejected those rumours.
The club also denied that they had placed a price tag of £18m on Saha's head.
A Fulham spokeswoman told BBC Sport: "There has been no contact from Chelsea for Saha, it is not true.
"It is also nonsense to suggest Fulham have put a price tag of £18m on Saha. None of these reports are true."
Cottagers' boss Chris Coleman and owner Mohamed al Fayed have insisted they will not be forced into selling the forward who has inspired Fulham to the brink of a Champions League place this season.
"You just get that feeling that we're being bullied into selling one of our players, but I don't like bullies and I don't like to be bullied so that's why we're so determined to hang on to Louis Saha," said Coleman.
Saha, who joined Fulham from Metz for £2.1m three years ago, scored his 15th goal of the season when he converted a penalty in the 2-1 win over Everton on Saturday.
Metz would earn around £1m from Saha's transfer to Old Trafford under a sell-on clause in the deal that saw him come to London.
