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 21-year-old has only made one appearance for City, as a substitute against Bolton in the Premier League in May 2011.
He has previously spent time on loan with Ipswich, Oldham and Blackpool.
During his time at Boundary Park last season he scored the winning goal against Liverpool in the FA Cup fourth round.
Wabara has represented England at Under-20 level.
