With news that N'Zogbia has not travelled with the squad on the pre-season tour of Austria it is anticipated that a transfer is now imminent.
Wigan Athletic chairman Dave Whelan told Sky Sports: "(The team) have gone to Austria today but 'Zoggy' hasn't gone. He's trained so hard that the boss (Roberto Martinez) has given him a couple of days off.
"He is a great footballer and he trains so diligently and he works so hard, he is a great lad to have around the club.
"If we do lose him, and we may well do, because he has expressed a desire to move on, we will miss him enormously. But he is a great asset for any football club who wants him.
"I have always said for £10million he is an absolute snip, if Stewart Downing can change hands for £20million I don't know what Charles is worth.
"He is the fastest, most direct wide player in the Premier League and I have always asked for £10million and hopefully we will get it and he will move on and be happy."
The DW Sports Fitness and Latics owner also moved to confirm that Aston Villa are not the only interested party and that the winger will be allowed to leave once a £10 million bid is received.
"He only has 12 months left on his contract," added Whelan, "I would love to keep him, he is a great lad and a fantastic player, but everything being as it is we have to be sensible and if we get a decent offer, and Charles wants to go, as usual I will honour what the player wants and let him go."
"(Villa) are not the sole bidders, there are another couple of clubs who are desperate to sign him.
"It depends how much they can pay up front, because we have got to re-spend that £10million this season just to replace Charles."
