Aleksandr Kolarov chose Manchester City because of their ambition to win the Premier League and Champions League. The Eastlands club, who narrowly missed out on qualification for club football's showpiece tournament last season, completed the signing of the Serbia left-back for a reported £19million fee on Saturday.
"I'm very excited to be here at a great club like Manchester City. Even the training ground is fantastic, better than Lazio's," the 24 year old 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 Premier title and the Champions League. For a young player like me, this is the best opportunity. It's the dream."
Kolarov, who has already been granted a work permit but will not join the club's pre-season tour of America, added: "I know a little of the history of Manchester City, I know that it is over 30 years since the club won a trophy.
"We want to change that and win a trophy soon for the fans."
