Javi Garcia says Manchester City are the biggest club in the country.
The 25-year-old feels his new employers have the potential to become a European heavyweight under the guidance of Roberto Mancini and their ambitious owners.
"Without a doubt, I'm at the biggest club in England and one of the biggest in Europe," said Garcia.
"So I'm very proud but also aware that I'm joining a great side full of top players.
"The Champions League group is a tough one but it'll be a lot of fun. The Real Madrid game is a great way to start out but we have the team and players to compete against any opposition."
