Jose Mourinho was certainly not shy of a controversial comment when he was managing any of Chelsea, Manchester United or Tottenham Hotspur in the Premier League.
The ‘special one’ was often also the one who was willing to shoot from the hip – Mourinho certainly wasn’t afraid of verbal confrontation.
During his time in charge at Chelsea, a period which is still recognised as the most decorated of his career, Mourinho often dueled with Arsene Wenger on the touchline, just to give one example.
Mourinho was an excellent character for the Premier League, and one that will be missed by the football world when he one day retires.
That being said, the Portuguese manager has already named who he considers to be the worst Premier League manager of all time, sharing a heated back and forth with Frank de Boer in 2018.
Jose Mourinho wasn’t impressed by Frank de Boer at Crystal Palace
On the pitch, De Boer will always be remembered as a legend for the Netherlands, a player who starred for both Ajax and Barcelona at club level too.
However, as a manager of Crystal Palace, De Boer manifested a slightly inferior reputation, at least in the eyes of Mourinho.

Speaking in his press conference back in 2018, Mourinho hailed De Boer as the ‘worst manager in the history of the Premier League’ – he didn’t mince his words.
Mourinho took aim at De Boer after the Dutchman claimed that he wasn’t the right man to help Marcus Rashford at Manchester United, who he was in charge of at the time.
Replying to those comments, Mourinho said: “I read something, some quote from the worst manager in the history of the Premier League – Frank de Boer.
“What he was saying was not good for Marcus Rashford to have a coach like me, because the most important thing for me is to win.
“If he was coached by Frank he would lose because he lost every game.”
Frank de Boer’s terrible record at Crystal Palace
Mourinho named the ‘most problematic’ player he worked with in his career too, and perhaps some Palace players will remember De Boer in a similar way themselves.
The Dutchman only lasted five games in charge at Selhurst Park, losing all four of his matches in the Premier League without scoring a goal.
Palace managed to win against Ipswich Town in the Carabao Cup in the midst of those defeats, but it wasn’t enough to save his job.
De Boer’s team were beaten by Huddersfield Town, Liverpool, Swansea City and Burnley all without scoring a goal.
And that probably explains why the Dutchman would be better advised to steer clear of Mourinho in the future.
