The 25-year-old Brazil midfielder is at pains, in an interview with Esquire magazine, to stress he expects to remain happy with the European champions.
"I'm very happy at Milan - and I don't expect that situation to change," he said.
"But if you want to talk hypothetically, if I were ever to leave it would have to be for a club of equal stature - and I think I would only find that in England or Spain.
"As for Chelsea and Liverpool, they are more tactically-oriented; they base themselves on solidity and organisation. They are maybe less creative, but they have good managers. I especially admire (Rafael) Benitez."
