Marouane Fellaini is a doubt for Manchester United’s clash against Arsenal after being sent back to his club from international duty.

Belgium manager Roberto Martinez revealed on Tuesday afternoon that Fellaini had returned to Old Trafford with an injury sustained in the club’s 3-1 win over Swansea on Sunday.

“‘Fellaini picked up an injury against Swansea City and will go back to his club,” Martinez said, as quoted by the official Belgium website. “We have a core of 24 players and that is enough.”

Fellaini, 28, has made 12 appearances for United so far this season and has become one of Jose Mourinho’s most trusted squad members.

His eight Premier League starts is more than any other United central midfielder bat world record signing Paul Pogba, with Ander Herrera selected six times and Michael Carrick on one occasion.

Central midfielder Fellaini played the full 90 minutes as the Red Devils defeated Swansea at the Liberty Stadium and flew out to train with Belgium ahead of their friendly against Holland on Wednesday and their World Cup qualifier against Luxembourg on Sunday.
