Wigan could face a fight to keep in-form forward Victor Moses after the player's agent indicated he has halted talks over a new deal.
The 21-year-old Nigeria international, who joined Latics in a £2.5million move from Crystal Palace two years ago, has just one more season remaining on his contract. Wigan have been trying to discuss an extension since December but agent Tony Finnigan says Moses has now decided against it.
Finnigan said: "An offer was made some months back - turned down - and we were still in negotiations. In the last week we spoke again and the player has now decided, 'I don't want to extend my contract'."
Wigan pulled off a coup to sign the highly-rated Moses from Palace and his performances since, particularly in the latter half of this season, have earned rave reviews.
The former England Under-21 winger has been inspirational over the past month as Latics have enjoyed a resurgence to pull clear of the Barclays Premier League relegation zone.
Roberto Martinez's side have spent most of the campaign in the bottom three but are now five points clear of danger after impressive wins over Liverpool, Manchester United and Arsenal in recent weeks.
Finnigan points out there is no animosity between Moses and the club but the player has simply decided not to renew.
He said: "It doesn't mean he doesn't like his manager - he chose Wigan over other clubs. Martinez is a tactical genius and an excellent coach, and they are Victor's words.
"He's been playing regularly, he's in form and enjoying his football. He has been offered the chance to extend his contract but has said, 'No thank you'."
Moses, who represented England at under-age levels but pledged his international future to the country of his birth earlier this year, could now be targeted by other clubs this summer.
