Manchester United are set to lose midfielder Marouane Fellaini according to the Mirror.

Per the source, the Belgium international is expected to leave at the end of the season as a free agent.

Fellaini has just a few months remaining on his current contract but no agreement has been reached over a new deal.

The Daily Mail meanwhile report that Jose Mourinho has grown increasingly frustrated with the Red Devils inability to tie down the futures of key players.

The United manager insisted a month ago that all parties were keen to reach an agreement but talks appear to have broke down.

The report claims that Anthony Martial and Marcos Rojo held talks with the club in December but are still waiting for a proposal.

The delay in talks is reportedly one of the factors why Fellaini is likely to look for a new club this summer.

Fellaini has had no shortage of interest from Turkey.

Turkish-Football have reported sources from Besiktas and Galatasaray both declaring an interest in Fellaini and holding talks with his representatives several times this season.

The 30-year-old is currently sidelined with a knee injury.

The experienced midfielder has scored four goals and provided one assist in 16 appearances for United in all competitions this season.
