Roberto Martinez says Wigan would only sell Charles N'Zogbia to a Champions League side.
The French winger has gone from strength to strength after joining from Newcastle in 2009 and is now an integral figure for the Latics.
The 24-year-old impressed this season and Martinez knows that he will eventually leave the DW Stadium.
However, Martinez has stressed Wigan are under no pressure to sell and says a deal would only be struck if it was a club that took his career forward.
Martinez believes that keeping N'Zogbia at Wigan is more important than any possible signing they could make during the transfer window.
"Charles has improved every year, scored 10 goals a season and taken on more responsibility by being captain," said Martinez.
"He knows I wouldn't stop his career progressing. But he also knows I wouldn't like him to go anywhere for the money as he's still 24.
"There are certain players who can compete in the Champions League and you can't stop those players.
"As well as Charles, there's a few who fall into that category.
"If the timing and price is right, then it can happen. But if I don't see a club who can offer him a different project than ours, then we won't sell.
"We don't have to sell and to keep the group is more important than any signing."
