The pair became friends at Inter Milan.
"People have put me on Mario's level and say I do stupid things," he told the Daily Mail, "they are always searching for something. If I dropped a water bottle, it's like I've dropped a bomb. Everything was a big drama.
"English people didn't have a good experience with Mario in the same way. I have to say he's a very good guy.
"The thing is with Mario, he acts without thinking. He just does stuff. That's his problem.
"When Mario says: 'I'll buy a car today', 10 minutes later he buys one. He doesn't think if it's good or bad. He just does it.
"He wants to help people. He is a friend. I speak to him a lot but every two or three weeks he changes his number. So I've lost touch with him since I came to Stoke."
