Should United and Mourinho part ways, the choice of his successor will be crucial as the Manchester club look to return to competing with the likes of City and Liverpool in the Premier League title race. Undoubtedly, that is a trend that needs to stop.
With that in mind, this is the starting XI Jose Mourinho has chosen for Saturday's match against Newcastle United at Old Trafford.
Mata, though, pulled a goal back when he curled in a free kick in the 70th and, five minutes later, Anthony Martial cut inside after swapping passes with Paul Pogba to equalise with a venomous low shot.
United supporters already have to face uncertainty about what the future would hold in the post-Mourinho era, but there might be another area of concern for them.
According to the Mirror, Mourinho has lost the confidence of the board with "senior United sources" telling the paper that the Portuguese coach's almost two-and-a-half-years in charge will end whatever the outcome of the league game against the Magpies. I've got to stand up and say "I'm not good enough to do this".
"No, I think we have enough potential to do better than what we are doing in the Premier League", he said at his press conference, which was scheduled at the earlier than usual time of 8am.
'I am mature, I can live with it, but I think some of the boys, in spite them not being the man that is hunted, are not coping well with it.
"At the end of the day this is going on for five or six years and I have to say Jose Mourinho is one of the best managers in the world".
Asked who was to blame for United's predicament, Mourinho responded: "The same people that were to blame for the fantastic season of last season".
Senior club players called for his sacking in December itself but the owners made a decision to stick with him until Manchester United mathematically failed to enter the Champions League.
"We gave ourselves a chance and we're disappointed not to have carried it [the performance] out for 90 minutes", he said.
"I couldn't believe they were still singing their songs with that scoreline, and this was the same feeling", he said.
I think any manager would struggle at Manchester United, with the way in which the recruitment is handled, the way in which it operates.
Old Trafford was rocking by the end, though, after a comeback reminiscent of the Fergie days.
"At half-time we were losing 2-0 and the fans were magnificent to the team and that is fantastic", said Mourinho. I love that football club, I absolutely love it to death, it's been my life.
