Tottenham boss Jose Mourinho admits he lost his passion for the game while at Manchester United.
Before victory at West Ham, Mourinho finally admitted that he was unhappy in the north west of England.
"I have to admit, yes [I lost my passion]," Mourinho told BT Sport.
"When you are not happy, people feel it. Happiness can be used to influence people to be better and you can use it to influence people to be more enthusiastic. Yes, I have to admit, yes."
While Mourinho was relieved of his duties at United, he maintains his relationship with the club's executive vice-chairman Ed Woodward remains strong.
After being appointed as Pochettino's successor, Mourinho revealed that Woodward was one of the first to text and congratulate him on his new role.
