France fullback Gael Clichy says his transfer to Manchester City from Arsenal last year had transformed him.
The 26-year-old - who was a surprise selection by France coach Laurent Blanc at the expense of former captain Patrice Evra for Friday's 2-0 Group D win over Ukraine.
"It's funny, but I am a vastly different player this year since I moved to City," said Clichy.
"In my head, it is a turning point in my career.
"I wanted to see where it could take me. I do not regret it for a moment, as I have gained in self-confidence.
"It has been 10 years that I have played in the Premier League, which is not bad.
"I am champion of England and that is important in the life of a player, one fells stronger."
