Jose Mourinho insists he will not "run away or disappear" from his responsibilities after launching an impassioned defence of his Manchester United tenure.

The Portuguese has faced severe criticism over his tactics in the wake of United's dismal Champions League last-16 exit to Sevilla on Tuesday.

Mourinho was particularly panned for the defensive mindset the Red Devils set up with in the 2-1 defeat, as Wissam Ben Yedder's double put the tie beyond United.

But speaking ahead of United's FA Cup quarter-final with Brighton and Hove Albion on Saturday, Mourinho delivered an emotional 12-minute diatribe in his media conference, fighting back against his critics.

He said: "Life is good, I have an amazing job to do. 

"Yesterday I met a new person working in the club - different area to me, nothing direct with me - a person that came from another club. I asked 'Why did you decide to come?'

"He told me 'Because I did a fantastic job in another club and I know that I have a huge job to do so I have a challenge'. 

"I said well done, my decision was based on something similar. I could be in another league where the title is in the pocket, practically won before a ball is kicked.

"But I'm not there, I'm going to be here. No way are you going to change my mentality. For me, I don't know if you know the expression, there is a quote I like; 'In every wall is a door, every wall is a door'.

"I'm not going to run away, disappear, cry, because I heard a few boos. I won't disappear from the tunnel running immediately, the next match I'll be first to go out.

"I respect the fans, I'm not afraid of anything. When I was 20 years old, I was nobody in football, I was someone's son.

"And now, at 55, I am what I am, I did what I did because of work, because of my talent and my mentality, so they can be together. I understand that for many, many, many years it was really hard for people that don't like me to say 'Here he is again, he wins again'.

"So, for those months I win nothing, 10 months nothing. Last title I won was 10 months ago. I beat Liverpool, Chelsea, lose to Sevilla - it's their moment to be happy."
