He admits life in Italy is not the same as in England, although he does feel he is embarking on the biggest challenge of his entire career.
"I used to say the Premier League was more about heart and emotion," he told MUTV. "Serie A is more about brains and tactics.
"Every team in Italy is strong defensively. Every game is about tactics.
"It is not as beautiful as the Premier League. That is one of the reasons why the Premier League is loved around the world and Serie A is loved in Italy.
"It is more about the mentality and culture. But this is a really big challenge, the biggest of my career."
