The Portuguese head coach is facing an uncertain future at the north London side after Manchester United lost three of their opening seven games in the Premier League.
Manchester United went on a four-game winless run in all competitions during September and October to fuel talk of Mourinho losing his job before Halloween.
When the Red Devils were left trailing Newcastle United 2-0 inside ten minutes in their last league game before the international break, the former Real Madrid boss appeared to be on the brink.
However, Manchester United responded in the second half as goals from Juan Mata, Anthony Martial and Alexis Sanchez sealed a thrilling 3-2 comeback win.
The 20-time English champions are in eighth place and seven points behind Premier League leaders Manchester City, Chelsea FC and Liverpool FC.
Manchester United are already trailing north London duo Arsenal and Tottenham Hotspur in the race to secure a Champions League spot by virtue of a top-four finish.
However, the Red Devils can move to within four points of Chelsea FC if Mourinho’s side manage to end the west London side’s unbeaten start to the Premier League season.
Former Chelsea FC midfielder Essien believes his ex-manager Mourinho doesn’t warrant the sack at Manchester United.
“They’ve had a very bad start to the season,” Essien told the London Evening Standard.
“Knowing Jose and the players, I am sure they will work hard and start to change things around.
“He’s a good man, first and foremost, and he always knows how to get the best out of his players. He knows when things are not going right and he knows what to do and the words to say to pick them up.
“I am sure he will do that and hopefully things will begin to change for him.
“He is [charismatic in training]. He is always close to his players. He’s such a good man but people see him differently on camera. But, off camera, he is such a lovely person.
“It’s all part of the game. When things are not going right, clubs start making changes.
“It would be unfair [if United sacked Mourinho] but, as I said, it’s part of the game. Managers come and go but we’ll have to wait and see what happens.”
Mourinho took over the reins of Manchester United from Louis van Gaal in May 2016 after the Red Devils finished in fifth spot in the Premier League table under the Dutchman.
The former Inter Milan boss led Manchester United to glory in the League Cup and the Europa League in his first season at Old Trafford.
Manchester United finished in the runners up spot in the Premier League table last term but ended his second season in charge without a trophy.
