Jose Mourinho has expressed his concern over Marouane Fellaini's contract situation at Manchester United. The Belgium international, whose contract is due to run out at the end of the season, has scored four goals in eight starts for the club this season after signing a one-year contract extension in January. Mourinho admits he’s more worried about Marouane Fellaini’s contract situation than Luke Shaw’s. The former Everton midfielder is set to become a free agent and reports say the club are yet to offer him new terms. "I'm worried about Fellaini and not about Luke Shaw because Fellaini finishes his contract and Luke Shaw doesn't. " said Mourinho according to SunSports Fellaini scored four goals in eight starts for the club this season before suffering a knee injury while on duty for Belgium against Bosnia and Herzegovina on October 7. Six United players - including Luke Shaw - are technically out of contract next summer. And Juan Mata, Ander Herrera and Phil Jones are all in line for extensions before Christmas. Mourinho is reluctant to lose anyone on a free next summer, and wants to make sure he can at least get cash for any players who don't fit into his plans at Old Trafford.
