The Red Devils boss has been criticised in recent weeks following Manchester United’s disappointing performances in the Champions League.
Mourinho’s showed little attacking invention in a 0-0 draw with La Liga side Sevilla in the first leg of their last-16 clash in Spain.
Manchester United slumped to a surprise 2-1 loss to Sevilla in the second leg at Old Trafford mid-week to exit at the competition at the first knockout stage.
The 20-time English champions are in second place in the Premier League table but 16 points adrift of leaders Manchester City.
While Pep Guardiola has got his Citizens side to produce an exciting brand of football, Manchester United have failed to entertain their supporters.
The Red Devils have scored less goals than both Manchester City and Liverpool FC this term despite the £75m addition of Romelu Lukaku from Everton last term.
Speaking at a news conference on Friday about Manchester United’s style of play, Mourinho said:
“I’m here and I’m going to be here. No way am I going to change my mentality.
“For me, I don’t know if you know the expression, I don’t know if the translation to English makes you understand but there is a quote that I like, which is something like ‘every wall is a door’.
“I’m not going to run away, I’m not going to disappear, I’m not going to cry because I heard a few boos. I’m not going to disappear from the tunnel, running immediately. The next match, I will be the first to go out.”
Manchester United finished in sixth place in the Premier League table last term but the Red Devils won the Europa League and the League Cup in Mourinho’s first campaign at Old Trafford.
