The Portuguese coach was expected to be sacked regardless of the result against Rafael Benitez's side, but the team's dramatic 3-2 victory has changed things for the time being.
It led to a grandstand finish and Sanchez heading home in the 90th minute to end a four-game winless run and give the club a shot in the arm at a time when background backbiting was compounding poor performances.
After the report was released, multiple pundits - including former Manchester United defender Gary Neville - criticized Manchester United not for the decision to fire Mourinho but for leaking it the day before the match, theoretically undermining his standing and leaving him as a lame duck manager. "They were not ready for this level of pressure that the manhunting is bringing".
"And, yes, it is brilliant for them to go into an global break sitting on that result for the next two weeks. But for younger people I think "problem" - and I think in the first half they clearly showed that".
"The ones that read the papers, that are connected with social media, they thought maybe I had gone", said Mourinho. A sacking was unlikely after his side beat Newcastle 3-2 at Old Trafford.
However, Shearer doesn't think the win fixes their issues and has urged the United board to back the boss in January.
"This team defensively only conceded one more goal than Manchester City last season, and they are all over the place this year because they are constantly hearing their manager tell them they are not good enough", he said.
Newcastle took the game to Man United before the break, but it was a different story in the second half.
Juan Mata says Manchester United fans do not "deserve everything that is going on" and hopes the last-gasp comeback win against Newcastle gives the team a mental lift. We were meant to come back, meant to win.
The Blues have been in scintillating form since the start of the season and it is all set to be a cracker as Jose Mourinho takes on his former club.
