That is according to St Pauli technical director Ewald Lienen, who was less than impressed by the Portuguese’s comments after their goalless draw against Sevilla.
Mourinho was in a crabby mood at his post-match press conference where he defended his side’s dour display and had a pop at his medical staff after Ander Herrera picked up an injury.
Lienen thinks Mourinho has lost his love for the game, and speaking on Sky Deutschland, he said: “If I ever said such b******* as a coach, I would just quit.
“His explanation is an insult to anyone who loves football.
“If he has enough money but can’t be bothered any more, he should just quit.”

United saw less of the ball than Sevilla and mustered fewer shots but Mourinho claims it was an “even” game.
“The stats are what it is,” he said. “Sometimes you have 15 shots, but 13 of them were what I call ‘statistic shots’, so I really feel that the result reflects what the game was.
“You ask me, ‘is it a good result?’. I say, it’s not good, it’s not bad.
“We have two legs to play and we have one match to decide everything at Old Trafford.”
On Herrera’s injury, the outspoken boss said: “We didn’t play him to give him more work and more protection, but it looks like he was not fully fit.
“The medical department gave him fully fit. They gave him fully fit Saturday and he trained Saturday, Sunday, Monday, Tuesday, and he looked fit.”
