Schalke defender Sead Kolasinac has revealed Manchester United are interested in signing him in the summer.

The left-back has been a key figure for the German side and has been a regular inclusion in their starting lineup, since being promoted from the club's youth system to the first team. The 20-year-old has started in 20 league games this season.

According to talkSPORT, United were preparing a move in bringing Kolasinac to Old Trafford as a replacement for Patrice Evra next season. The left-back confirmed the Red Devils's interest in his services, but admitted that he will not rush into making a decision over his future.

"Yes, I have offer from Manchester United. But, I will not hurry with the decision [over my future]. I have to see what Schalke think about it," the Mirror quoted Kolasinac as saying.

United are without a permanent manager after they showed the exit to David Moyes. Ryan Giggs has taken over the role of the interim manager at Old Trafford and won his first game in charge, defeating Norwich City 4-0 at home.

Southampton star Luke Shaw has been touted to join United on a £30m transfer in the summer. However, the Metro claims the Saints left-back will not sign for the Red Devils until they appoint a new manager.

Evra is the first choice left-back at the club and his contract runs down at the end of the season. The Frenchman has not signed an extension and is likely to leave the club on a free transfer.

United will be looking to strengthen their defence in the summer transfer window. Nemanja Vidic confirmed his decision to join Inter Milan and Rio Ferdinand, along with Evra is in the final few months of contract at Old Trafford.

The Schalke defender has featured on the international stage with Bosnia, despite playing for Germany at under-18, 19 and under-20 level. He came up through the ranks of the Bundesliga's academy before being promoted to the first team in 2012.

Kolasinac is valued to be around £4.5m, according to talkSPORT. A move for Schalke star to Old Trafford would be a cheaper option for United when compared to Shaw.
