Former Manchester United manager Jose Mourinho claims that he felt trapped by English football because he wasn't allowed to speak his mind about match officials.
The Portuguese manager spent some of his best years managing in the Premier League where he won three league titles as well as five domestic cups.
As well as establishing a knack for winning in England, the former Chelsea manager also gained a reputation for his run-ins with the Football Association.
However, Mourinho still believes that he was unfairly punished and that the nature of English football restricted him from being able to give his honest opinion.
"I lived in England most of those years (the 15 years since he left Portugal)” Mourinho told Eleven Sports.
"I also spent some years in Spain where we walked there in the same habitat. Italy not so much. Italy really likes the game, the tactics. I usually have people talking about it, more polemic, less polemic, more aggressiveness, less aggressiveness, but they are people of great credibility and you have great names in football to discuss about football.
"But in England it's day and night. For example, I've sometimes felt almost caged because you can't even comment on the referee before the game. I was punished and well punished for pre-match statements and statements such as 'I hope the referee is very well, that he resists pressure from Anfield Road, that he has an excellent performance'. This is forbidden. This is considered to somehow induce the referee, put some kind of pressure on him.
"Even speaking well of the referee, as I did, I was punished. In Portugal, you tell referees what you want, before the game, during and after the game, you're punished with ridiculous small fines. There's total impunity. And we're talking only at this level. And then obviously we're a country that should like this.
"The kind of TV shows that exist in Portugal and that exist simultaneously in three, four, five different channels and that are repeated from Monday to Sunday and that survive, is because Portuguese people like this. So maybe we have the football we want to have."
