Jose Mourinho is more often than not a man with a chip on his shoulder. It could be irritation in the media, a need to create a siege mentality or that he is just in a bad mood.
This all seems to come to a head when he goes back to one of his former clubs and there will be an added intensity as he walks out at Manchester United as the Tottenham manager.
He took United to trophies, not least the Europa League in his first season, and was well liked for most of his time in charge.

He returns to Manchester United for the first time on Wednesday, where he was sacked in 2018
But it all unravelled and after defeat at Anfield at the back end of 2018, the mood had soured beyond repair. He was sacked and replaced by club legend Ole Gunnar Solskjaer, who soon transformed the fortunes during his time as interim boss.
Mourinho's long, esteemed career has seen him return back to Porto, back to Chelsea, and now back to Manchester.
And so, ahead of his first return to Old Trafford on Wednesday night, Sportsmail delved into the archives to look at each of his returns to his former clubs and reflected on how they panned out...
CHELSEA 2-2 Manchester United
October 20, 2018
Mourinho's last visit to west London as a football manager wouldn't have looked out of place in a West End theatre.
The Portuguese was in the thick of the drama as his Manchester United side conceded a late equaliser at the hands of his former employers. The Red Devils came from a goal down to lead 2-1 before Ross Barkley scored in the 96th minute to rescue a point.
Chelsea's technical assistant Marco Ianni raced to celebrate Barkley's strike in front of Mourinho, which saw the former Blues boss lose his cool after holding it together for large spells. He jumped up to confront Ianni and was then cooled down by United's staff members and substitute goalkeeper Sergio Romero.
He taunted the home fans at the final whistle with three fingers, indicating how many Premier League trophies he had won at Chelsea, after chants of 'f*** off Mourinho' echoed around his former home.

Mourinho entered the press room after this encounter visibly fuming, and could not wait to vent his frustrations on the way Chelsea had scored the only goal of the game.
The ball had already been planted in the back of the United net in the first half when Alvaro Morata forced Phil Jones to make the most comical of attempts of a clearance from a dangerous, in-swinging cross. Fortunately for the red-faced United defender, he was judged to have been pushed before pinging the ball into his own top corner on the volley.
Morata would, however, go on to have the decisive say in the match, rising in the 55th minute, unmarked, to power home a Cesar Azpilicueta cross. 'In the only period they were in control they score the goal,' said an irked Mourinho at the final whistle.
The Portuguese had been given a painful reception at Stamford Bridge by the fans who once adored him, and there was a distinct lack of handshake at the final whistle with his managerial counterpart Antonio Conte. The pair would go on to exchange snipes back and forth in the media for the remainder of the campaign. Tasty.

It was another miserable return to Stamford Bridge for Mourinho as his United side bowed out of the FA Cup.
N'Golo Kante got the only goal of the game early in the second half but this one was all about what was happening on the touchline as Mourinho and Conte were involved in furious debates following a red card for Ander Herrera.
Mourinho was fired-up on the touchline, pacing his technical area having lost his first return to west London 4-0. While this one wasn't a rout, it was another defeat and he said himself on his Tottenham unveiling, he will never be OK with defeats.
Constant stick and abuse from Chelsea fans was unlikely to have eased Mourinho's annoyance at how it panned out as Eden Hazard ran the show for the Blues to keep alive their hopes of a domestic double.

When Jose Mourinho was sacked for the second time by Chelsea in December 2015, the Blues sat 16th in the Premier League but still held him in high regard.
However, his return to Stamford Bridge as Manchester United boss was a day he'd no doubt like to forget. As the former Chelsea boss took his seat in the opposing dugout - a sight in itself - he received a warm reception from the home fans - having previously led them to seven major trophies. But his moment to soak up any affection was short lived.
Just 30 seconds into the match, Pedro took advantage of some questionable defending and Chelsea were ahead. It did not get better for Mourinho or Manchester United thereafter.
Chelsea went on to score four while the home fans could not help a dig at their former boss as 'you're not special anymore' went around the stands at Stamford Bridge.
Shook by the result and his reception, Mourinho turned his frustrations towards then boss Conte for trying to humiliate him in front of his former fans. A
