Leagues where 'the kitman can coach a team to the title' are not worth their salt in the eyes of Jose Mourinho.
While not specifically naming Pep Guardiola or Bayern Munich, the Manchester United boss joked that he'd not been wise to take on tough challenges in countries such as Italy and England.
"For me, I'm not the smartest guy to choose countries and clubs," the coach told an interview with France Football. "I could choose another club in another country where becoming the champion is easier.
"Maybe in the future I have to be smarter and choose another club in another country where everybody is champion. Maybe I will go to a country where a kitman can be coach and win the title."
In comparing the Premier League and Bundesliga title races, the Portuguese tactician was adamant that the number of different competitors in England makes it the toughest place to coach.
"In England, clubs are so economically powerful that the market is open to all," added Mourinho. "Take the example of Bayern in Germany.
"You know when they start winning the title every year? The summer before, they buy the best player of Borussia Dortmund. [Mario] Gotze, then [Robert] Lewandowski the following year, then [Mats] Hummels last year.
"Me, I arrive at a club that has a great and prestigious history, but that can no longer be declined in the same way.
"No club in England, whether it's Manchester United, Liverpool, Manchester City can no longer be dominant permanently. Power has divided."
Mourinho, 54, also discussed how he felt he'd matured since his firebrand persona days at the likes of Chelsea and Real Madrid, reflecting on his new found ability to switch off from the game.
"Mourinho the man tries to be the opposite of the manager," the United coach noted. "He tries to be discreet, calm; find the way to disconnect.
"I can go home and not watch a football game, not think football. I can do it. At the beginning of my career, I could not. I was constantly connected, 24 hours a day.
"I had to find a form of maturity. Today, I feel good with my personality as a man. I have matured, I am more peaceful. A victory no longer represents the moon and a defeat no longer means hell.
"I believe that I am able to transmit this serenity to those who work with me, to my players. I have the same ambitions as before.
"The same involvement, the same professionalism, but I'm more in control of my emotions."
