Mourinho signed a three-year contact with United in the summer of 2016 and made quite an impact in his first season.
With Unai Emery and Brazilian superstar Neymar not seeing eye to eye, it seems inevitable that the Spaniard will be replaced at the end of 2017/2018.
Moving ahead, it appears he won't be allowed to buy any new players this January transfer window, unless he first sells off the fringe players.
Manchester United manager Jose Mourinho is reportedly ready to demand that the club back him in the transfer market amid speculation linking him with Paris Saint-Germain.
The Premier League club's latest financial results were released in September and showed a significant rise in their wage bill, with an increase of 13.5% to £263.5m.
Since taking over in 2016, Mourinho has oversaw spending of nearly £300m in 3 transfer windows on 7 major signings.
The Old Trafford board want to control costs before sanctioning more outlay on new signings.
Yet bringing in the right players in January and next summer can also help narrow the gulf.
Shaw now seems certain to leave in January after injury problems and failing to generate trust from Mourinho.
As far as Jose Mourinho will view it, the club offers two things, then: the possibility to become a legend and the probability of making it happen.
But how do Manchester United fans view Mourinho's spell at the club as the Portuguese nears a year and a half in the job?
Against the rest of the big 6, Manchester United have picked up only 4 points out of a possible 9, in contrast to title favourites Manchester City, who have already beaten Chelsea, Liverpool and Arsenal. By the day, this is becoming a major topic regarding the future of Mourinho.
On the pitch, Mourinho's men suffered a setback at the weekend after the 1-0 defeat at Chelsea saw them slip eight points behind league leaders Manchester City.
