Fernando Torres is returning to Atletico Madrid on loan until the end of the 2015-16 season.
Steve Clarke is hoping to keep Glenn Murray at Reading after his loan deal expired following the 2-1 win over Norwich.
Wigan manager Roberto Martinez has admitted he may struggle to keep Victor Moses at the DW Stadium.
The 21-year-old has impressed of late against the Premier League's top sides, including a brace in the 4-0 demolition of much-fancied Newcastle United.
However last month he broke off contract talks as the Latics face up to the fact they could lose one of their prize assets.
Martinez is refusing to be drawn on the future of his promising striker but is well aware that an approach from a more established Premier League club could tempt Moses away from Wigan.
"You cannot stop players going to the next moment in their career and the potential of Victor is incredible," Martinez said.
"As long as the club gets the right price and the player gives everything they have got for Wigan, then our chairman Dave Whelan will never stop them from moving upwards.
"It happened last year with Charles N'Zogbia and it would be unrealistic of us to think we will never lose players.
"Victor has the quality to go as high as he wants to. We sometime forget he is only 21 and we don't want anyone to feel stale here.
"He is enjoying his football and if he attracts admirers from outside the club, that's because he is doing well and Wigan are doing well."
Martinez himself is the subject of speculation after being hotly tipped to succeed Roy Hodgson at West Brom having previously turned down Aston Villa last summer.
The Spaniard is remaining focused on securing top-flight football though, with Wigan sitting three points above the drop zone with two games left to play.
"My concentration is on the next two games. I am not thinking about anything else. I signed a new contract last year and, in my eyes, there is nothing more important than Wigan," he added.
