The Portuguese’s relationship with the Stamford Bridge faithful deteriorated towards the end of his second stint at the club, with Mourinho often complaining about the atmosphere.
This breakdown in relationship between Mourinho and the club, including a number of high-profile players, eventually culminated in his dismissal last season.
Mourinho quickly returned to management and was unveiled as the new United boss last summer.
Writing in a season ticket renewal brochure for the club, Mourinho recently said the passion of United’s supporters was unrivalled by any of the other sides he’s worked with.
“I have to say I’ve been impressed by your dedication and commitment, as season ticket holders here at United,” he said.

1/22 David de Gea - 7 out of 10
Had no answer to Gabbiadini's strikes, but made good first half saves to deny Tadic and Ward-Prowse.
2/22 Antonio Valencia - 6 out of 10
Was given a difficult afternoon by Redmond, but utilised his experience as the game grew old.
3/22 Eric Bailly - 6 out of 10
A shaky start in which he was troubled by Bertrand's pace. Another who improved in the second half.
4/22 Chris Smalling - 7 out of 10
Had his hands full with Gabbiadini, but demonstrated fine positioning and awareness.
5/22 Marcos Rojo - 5 out of 10
Uncomfortable at left-back although he was pivotal in laying on Lingard's goal.
6/22 Ander Herrera - 8 out of 10
Oozes class at times, emphasised by his pinpoint cross for the winner. Occasionally guilty of chasing the game.
7/22 Paul Pogba - 6 out of 10
Fielded in a deeper midfield role, his bursting runs were impressive but few and far between.
8/22 Juan Mata - 5 out of 10
Saw little action and was replaced at the break for the more positioned-minded Carrick.
9/22 Jesse Lingard - 6 out of 10
Kept a cool head to score another Wembley goal, but almost lost it when fouling Redmond when on a yellow card.
10/22 Anthony Martial - 5 out of 10
Kept under wraps by Cedric for long periods, his deliveries were questionable.
11/22 Zlatan Ibrahimovic - 9 out of 10
The biggest man for the big occasion. Started and ended the scoring to win his first major trophy for Manchester United.
12/22 Fraser Forster - 5 out of 10
Questioned for his positioning for Ibrahimovic's free-kick, there was little he could do with the other two United goals.
13/22 Cedric - 7 out of 10
Lacked discipline at times, but impressed when on the attack and delivering from the right.
14/22 Jack Stephens - 6 out of 10
Yellow carded for a tough challenge on Martial, the youngster competed fiercely.
15/22 Maya Yoshida - 6 out of 10
Executed a great tackle to deny Lingard. Occasionally allowed his opponents too much space in the area.
16/22 Ryan Bertrand - 8 out of 10
Like Cedric on the other flank, the full-back was excellent in getting forward and crossing at pace.
17/22 Oriol Romeu - 7 out of 10
Competed well against Herrera, and almost won the tie himself with a header that crashed against the post.
18/22 Steven Davis - 8 out of 10
The captain was a delight in midfield. He held his position well and was at the heart of Southampton's best play.
19/22 Nathan Redmond - 7 out of 10
An exciting talent but too often tried to be hero, shooting when teammates were better placed.
20/22 Dusan Tadic - 7 out of 10
Had a habit of finding pockets of space between United's defence and midfield in which he could show off his close control.
21/22 James Ward-Prowse - 8 out of 10
Wonderful distribution, particularly from dead ball situations. Able to weight passes beautifully.
22/22 Manolo Gabbiadini - 9 out of 10
Southampton's new hero scored twice and had another incorrectly ruled out. Deserved to end the match as a cup winner.
“I’ve managed several clubs and I have never seen such unrivalled passion. The stadium is full every time we play and the support the players receive is special.”
In contrast, speaking about Chelsea’s atmosphere in his second spell with the club during the 2014/15 season, Mourinho criticised the crowd for its lack of support.
“I can clearly say we are the team to get less support in home matches,” he complained. “I think it’s getting worse.
“When comparing to my previous time, I think it’s getting worse. I don’t question the passion and the love – I’ m nobody to question that and I know clearly that’s not true.
“Chelsea fans show us their passion for this club every day, but there is a certain line of living (way of behaving) at the matches at Stamford Bridge.”Reuse content
