Wigan's chairman, Dave Whelan, has accused Chelsea of "taking the mickey" with their bid for the winger Victor Moses.

Whelan confirmed that the Champions League winners had made an offer, reported to be £4m, on Monday night. It 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 Martínez 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."
