Manchester United manager David Moyes has claimed that midfielder Marouane Fellaini has found the transition from Everton to Old Trafford "difficult".
The Belgium international joined the Premier League champions last summer for a fee of around £27m, but has failed to make a significant impact at the club.
"It's not an easy move coming to Manchester United, as I can tell you," The Express quotes Moyes as saying.
"For Marouane, I think it's proved equally as difficult, but I have to say I think he has done a lot of good things and he has improved."
United will take on Newcastle United at St James' Park on Saturday in the Premier League.
