Thus, the reason for United to play defensively surprises and angers me.
It has admittedly been increasingly hard to stay positive with him at United.
And the Belgium global, who hit his fifth Champions League goal of the season in the defeat, was critical of his team-mates.
Hardly the words United fans would want to hear.
Mourinho has claimed on a number of occasions this season that he has matured and during his early days as United manager, he resembled a son in law who had recently met his in-laws and was trying to stay on their good side.
The Belgium worldwide spoke to BT Sport after the final whistle and began by describing the scenes in the home dressing room, where the players were understandably gutted. There was Ashley Young on his honkers, looking spent.
And they also supposedly booed Jose Mourinho at full-time as he walked towards the tunnel.
"I sat in this chair twice in the Champions League", Mourinho said. "It is not something new for the club".
"That's football, we lost, but tomorrow is another day and Saturday is another match".
"Today we are in the King's Cup final and in the quarter-finals of the Champions League".More news: Twitch Offering More Free Games to Prime Subscribers Each Month

"I think the intention; the way we started was really good and really positive". "Sevilla were better than us, so they deserved it". By saying that the club is not unfamiliar with losing in Champions League knockout matches, he has taken a big risk, with fans not exactly happy with that statement. In the first half I do not remember a risky situation for them, so I think it was a good controlled performance by them without any kind of danger. The lack of urgency in the English side's play was palpable and the crowd continued getting restless as the second half seemed to bring about no visible change in approach.
"The first goal will be always important in this match not just because of the first leg result but also because of the style of the match".
"Then they scored the first goal and from that moment on we tried to chase the game".
Marcus Rashford, so brilliant on the left with his two goals in the North West derby, was moved to the right flank while Alexis Sanchez, who had looked promising playing just behind Romelu Lukaku, was switched back to the left wing. It's a natural process.
However, this did not stop the United boss from insisting that he needs to spend more money in the coming transfer window.
And therein lies the kicker.
"Sometimes I'm lucky with changes and sometimes other managers are lucky with their changes", Mourinho added.
In a way, we should marvel at such brazen self-service; you don't see this in normal day-to-day life.
However, Salah is still in contention for the Premier League highest goal scorers' award at the end of the season - with 24 goals, same as Harry Kane of Tottenham Hotspur.
But Mourinho's declaration that he does not have regrets betrays a man who will not change.
So far, United aren't even meeting that minimum demand from their supporters and it is questionable how long they will remain patient while it is inevitable that comparisons between Mourinho and Guardiola will continue to be made.
