Chelsea boss Jose Mourinho has no doubts the Premier League is best competition in the world.
Mourinho believes that of all the major European leagues it is the Premier League that provides the toughest challenge for a coach or a player.
He told the London Evening Standard: "For me the situation is clear - the best place to develop is in the most difficult league. In England, you don't do 100 points, you don't score 125 goals unless Manchester City can do it this season. But normally the evolution of a player needs difficulty and the difficulties help the development of a player.
"Of course it is easier to succeed abroad. You go to Spain and there are two big clubs (Barcelona and Real Madrid); you go to Germany and they have one big club (Bayern Munich) and a little bit more.
"If you are an attacking player and go to Barcelona or Real Madrid, it is easier to score 50 goals than if you're playing in England.
"Of course, these clubs are a big attraction. You can't blame a player. As a manager I had that instinct, too. I wanted to go to Madrid myself. So if a player has that feeling it's very understandable.
"But I keep thinking in my case, where I enjoyed it most is where the competition is. It's high here. If I was a player I wouldn't leave the Premier League."
