Manchester United's derby triumph will go down as the day Paul Pogba inspired a turnaround but for me, this was more about Jose Mourinho.
Pogba cannot get sacked but Mourinho can, so do not underestimate how enormous this result was for the United manager. It was a massive statement.
It was one to win over the floating voters, one to convince any fans who were starting to wonder whether Mourinho was still the right man for the job.
If United had lost that game 2-0, 3-0, 4-0 or worse, then you would have had to stand back and think, where does Mourinho go from here?
