Bastian Schweinsteiger is one of several players Manchester United are open to selling this summer, according to Sky sources.
The German midfielder could be allowed to leave Old Trafford as new manager Jose Mourinho reshapes his first team squad.
He was left out of the United squad for Saturday's friendly with Galatasaray in Gothenburg.
Sky sources also understand 23-year-old forward Will Keane could leave the club.
Mourinho will continue to assess his squad before deciding on further departures.
Schweinsteiger announced his retirement from international football on Friday, having made 120 appearances for his national side, and was a key part of Germany's World Cup triumph in 2014.
Louis van Gaal bought him to Manchester United from Bayern Munich for £6.5m in July 2015. He has made 31 appearances for the club, scoring once.
Schweinsteiger is one of the most decorated players in Bayern history, having won eight league titles and seven German cups during his 13-year career there, as well as the Champions League.
Last season's FA Cup was his sole trophy with Manchester United.
