Wigan chairman Dave Whelan has accused Chelsea of "taking the Mickey" with their bid for winger Victor Moses.
Whelan confirmed the Champions League winners made an offer, reported to be £4million, on Monday night which was immediately rejected.
The Nigeria international has only 12 months of his contract remaining and while talks have stalled on a new deal Whelan is not prepared to allow the 21-year-old to leave on the cheap.
"Chelsea would need to get realistic before we would even listen to them," he told ESPN.
"They made a bid at 6pm last night and we turned it down flat. Roberto Martinez has brought this player on and he needs at least another year with Roberto to become a top player.
"We have offered him a new contract but it seems the agent, more than the player, wants to move him on - at least that is the impression we are getting.
"It cannot be for the player's good. Victor Moses needs another year or two before moving to a club like Chelsea.
"He needs games and he won't be first choice at Chelsea, I wouldn't have thought
"We don't need to sell him with 12 months to go on his contract because he is under 24 so wouldn't be going on a free transfer.
"Ideally we would like him to sign a new contract, or a club like Chelsea would have to be realistic.
"At the moment, they are taking the Mickey with the bid they've made."
