Manchester United face an uphill job to win the Premier League after the club suffered a home defeat against neighbors Manchester City.
Mourinho must boost his side in the winter transfer window and while doing that must also hold on to the key players in his current squad.
The former Chelsea and Real Madrid boss likes Marouane Fellaini a lot, the former Everton midfielder will be out of contract next summer and can look to agree a pre-contract with any club next month.
If reports making rounds are anything to go by then Mourinho has held crisis talks with the 30-year-old midfielder and wants him to remain at the club.
According to an exclusive report covered by The Sun, Manchester United have moved in and offered the former Everton star a two year deal worth $18million ($173,000-a-week) to stay with the Red Devils.
The British source have mentioned that Mourinho has convinced Marouane that he will get enough playing time. This season, in 12 appearances, Fellaini has scored 4 goals and provided one assist.
