Wigan boss Paul Jewell has revealed defender Pascal Chimbonda handed in a transfer request on his way off the pitch after Sunday's defeat by Arsenal.
Jewell says Chimbonda will not leave the club for less than £6m
"I was shaking the players' hands as they came off to congratulate them on a magnificent season," said Jewell.
"He came up to me, still in his kit, and handed me a transfer request, along with a note to thank me and the club for all our help. I was livid."
Latics chairman Dave Whelan says the 27-year-old can only leave for £6m.
The Frenchman joined Wigan for £500,000 in the summer of 2005 and, after impressing for the promoted side, he signed an improved four-year contract in January.
In recent weeks, he has been linked with a move to Tottenham and Jewell revealed the club had held talks over his future.
"We have had two meetings this week with him to discuss the future and had made it clear we would not stand in his way if the right offer came along," he added.
"So to then be treated this way shows a quite spectacular level of disrespect to myself, the chairman, to all his team-mates and to the Wigan supporters, who have supported him this year.
"I reiterate the player will not go on the cheap. The price is £6m and we will not let him go for less."
Chairman Dave Whelan was also angered by Chimbonda's behaviour.
"The timing of the request was absolutely diabolical," he said.
"I have said to him we will not stand in his way because we cannot afford to have players at this club who do not want to play for us.
"However, the price is £6m, not a penny less. If anybody wants to pay that, they can buy him. If they don't, he can play in the reserves until his contract is over."
However, Chimbonda's agent Willie Mackay insisted he had not been behind the player's actions on Sunday.
"I never got Pascal to do anything. He did it himself," insisted Mackay.
"We will now see what happens. It's up to Dave Whelan. He is the chairman, he holds the contract and he can say what he wants."
