Schalke goalkeeper Manuel Neuer, believed to be a target for Manchester United, has indicated he could leave the club at the end of the season.

With Edwin van der Sar set to retire from football at the end of the season, United are on the look-out for a long-term successor to the Dutchman.

Neuer has long been linked with a move to Old Trafford, and with Schalke struggling in the Bundesliga this term - they sit second from bottom with just one win all season - he is ready to move on to make sure he continues playing European football.

He will move into the last year of his contract at the end of the campaign meaning Schalke will have to cash in if he will not pen a new deal.

Germany's goalkeeper at the World Cup finals told the Daily Mail: "I am not comfortable with the current situation at Schalke. I hope we can turn the corner and get back on track.

"My contract runs until 2012 and I have always made it clear that I would play this season for Schalke. As for the future, we will see. I want to be playing in European competition next year."
