"England? Over there defenders kick the s*** out of you and nothing gets given by referees," Higuain told Marca.
"They're built like wardrobes and they hit you. I suffered a lot in the English league. I did not manage to adapt in six months. It has nothing to do with the Spanish League.
"I don't know how it could impact Leo, but being a player of another level I don't think he would suffer, but it's a very complicated league."
On Messi reportedly being unhappy at Barca, Higuain added: "I don't know what Leo Messi might be thinking.
"I hope he decides what he feels will make him happy. That is the most important thing in a decision.
"Choosing what one feels will make him happy, not what will make the other happy."
