According to the 'Daily Mail', Manchester United would be happy to let Fellaini go for the right price, but are not keen on letting him leave on a temporary deal.
The former Everton man is reportedly wanted West Ham and Sunderland, but both clubs would struggle to afford the midfielder's wages.
It is understood that Jose Mourinho will continue to spend and strengthen his squad, meaning that Fellaini will fall further down the pecking order, but whether any interested clubs could afford the Belgian remains to be seen.
Since joining for £27.5m from Everton in 2013, Fellaini has failed to impress at Old Trafford, making 106 appearances, scoring 13 goals.
