Manchester United boss Jose Mourinho has expressed his delight following Marouane Fellaini's decision to sign a new contract with the club.
The Belgian midfielder has extended his stay at Old Trafford until at least 2020, and his manager has admitted that he is "very happy" with the development.
"I am very happy Marouane is staying with us," Mourinho told the club's website.
"I always believed in his desire to stay with the club and I am delighted that he has signed a new contract."
Fellaini, who joined United from Everton in 2013, is currently on international duty with Belgium at the World Cup.
