Marouane Fellaini has agreed a deal to join Besiktas at the end of the season, according to reports.
The 30-year-old midfielder's contract at the Premier League side Trafford runs out in the summer and looks likely to leave on a free transfer.
The Turkish news outlet Fotomac says the Red Devils ace has signed a pre-agreement with Sunol Gunes' men.
It's understood that Super Lig club's Galatasaray and Fenerbache are monitoring Fellaini's situation.
United head coach Jose Mourinho reportedly urged the United board to pull out all the stops and offer the Belgian a new deal at Old Trafford.
However, the Belgium international, according to SunSport, has no intention of penning a new contract, and seeks a fresh challenge.
