The 24-year-old is looking forward to get started at his new club.
“I’m very excited to be here at a great club like Manchester City. Even the training ground is fantastic, better than Lazio’s,” he told the club’s website.
“I’m coming back early next week to train with the players who aren’t touring America. I want to start as soon as I can, and I can’t wait to meet all the other guys.
“I had the opportunity to join other teams – the names are not important. When I spoke with Mr Mancini, my choice was Manchester City because I know they are a good team. I think maybe a great team.
“The Premier League is the best in the world and he wants us to go further and win the title and the Champions League.
“For a young player like me, this is the best opportunity. It’s the dream.”
