Manchester United midfielder Marouane Fellaini has reportedly been spotted in Istanbul, sparking speculation about his future.

The former Everton player has been linked with a move to Besiktas, as well as fellow Turkish outfits Galatasaray and Fenerbahce.

Fellaini has not featured in Jose Mourinho's United side since the end of September due to a knee injury that he suffered while on international duty with Belgium.

The 'Besiktas Talk' Twitter profile posted a video, which is believed to have been filmed by a member of the public, of Fellaini allegedly wandering around the Swisshotel in Istanbul.

The 29-year-old has started just three Premier League games this season so far.
