Wigan Athletic chairman Dave Whelan has confirmed the club will not stand in Charles N'Zogbia's way if a top-six club comes knocking.
The French winger is again in demand in the January transfer window with Sunderland now believed to be in the hunt for the 24-year-old's signature.
The Black Cats are thought to be tracking the former Newcastle man following the sale of star striker Darren Bent to Aston Villa for £18million.
Whelan has reiterated that Wigan will let N'Zogbia speak to interested parties if they are a top-six club, and Sunderland currently sit sixth in the standings.
However, the Latics supremo insists that Wigan will only agree a fee for the 'right money' as he is an 'outstanding' player.
"I've always said to Charles if a top-six club comes in for him, he can speak with them," Whelan told the Manchester Evening News.
"We'll never stand in a player's way. We don't want to sell him, we've no plans to sell him and we haven't received any offers at this stage.
"There's no chance of him going anywhere on loan and if he is to go, it has got to be for the right money. He's an outstanding player, he has wonderful pace."
Meanwhile, manager Roberto Martinez does not want the transfer window to distract his side from retaining their top-flight status.
Wigan are currently in the bottom three despite a run of just one defeat in seven games, and reports have linked the Spanish boss with moves for a number of players.
But with games against Arsenal and Aston Villa on the horizon, Martinez is concentrating on points rather than purchases.
"We are focusing on the games in front of us," he said. "We have a game with Arsenal and a game with Villa and they need our full concentration.
"We're not going to be distracted by people's futures or by speculation.
"We need to concentrate on the team. The transfer window is great for the media and people on the outside, but we need to keep our focus."
