After the departure of Sir Alex Ferguson, Manchester United finished the season in the top four only once in four years.
David Moyes did not even finish his first season until the end, and Louis van Gaal paid for the inability to secure a place in the Champions League in his second campaign.
And although Mourinho failed to immediately fix the situation in the Premier League, he led the Red Devils to victory in the Super Bowl, the League Cup and the European League, which guaranteed the club the participation in the Champions League next season.
The Portuguese recently noted that he would like to coach Manchester United for 15 more years, but insists he intends to leave the club in a better condition than he took.
"I would like the next manager to take the club and the team in a much, much, much better state on every level than I do," said Mourinho.
"I discovered an amazing club with an amazing history, but he was not ready to win. I want to win and I want the same for the next coach ".
