Wigan chairman Dave Whelan has revealed the club "have to sell" winger Charles N'Zogbia. Dave Whelan: "We have to sell Charles N'Zogbia because he's on the last year of his contract. "We can't keep him if a big club comes for him and he does deserve a big club because he's that kind of quality player. "We've got a lot of good players and it is understandable people are looking at them. "There's been a lot of media speculation - that is part of being in the transfer window - but I am more focused on trying to reach the targets we set. The players are under contract. "We would love to keep him and pay him what he wants to stay with us but it's a very difficult situation. "He's such a great player and we are such a small club sometimes we don't go together."
