Manchester United are close to agreeing a £21.5m deal to sign Borussia Dortmund midfielder Ilkay Gundogan, according to Sky sources.
Louis van Gaal says Manchester United have offered David de Gea "a lot of money" in a bid to keep him at Old Trafford.
The 20-year-old former Wigan trainee is yet to make a first-team appearance for the Latics but he is currently first choice at Northampton in League Two, where he is on loan.
Wigan boss Roberto Martinez told www.wiganlatics.co.uk: "Seeing Lee's progress from a young age has been a joy and to have him stay here and continue his hard work is great news.
"Lee is a great goalkeeper and he has shown that at Northampton this season. He has had some outstanding performances and we are really looking forward to continuing to work with him."
