London's neighbor should be joined by attacker Victor Moses in the near future.
One offer from the capital team has already been rejected, as "Wigan" will only say goodbye to their leader for 10.7 million euros.
"I've talked to the chairman of Chelsea - it's not difficult to negotiate with them," said Wigan manager Dave Whelan. "We've stated our price and will await a response: either it will be accepted or not. Of course, we would like Moses to sign a new contract, but we won't stand in the way if we agree on suitable conditions."
Last season in the Premier League, Moses scored six goals in 38 matches.
According to the press, "Chelsea", who have spent 88 million euros this summer on new players, is also actively interested in Bayer Leverkusen's representative Andre Schurrle.
