Michael Bradley has said that signing for a club like Roma is a 'once in a lifetime opportunity'.
Bradley completed a move to Rome from Chievo on Sunday for £3.75m euros and has vowed to prove he deserves to wear the famous shirt.
The American midfielder told asromanews.it: "This club believes in me and I have proved that I am worthy of wearing this shirt.
"This chance only comes once in a lifetime. Now I want to show that I can earn a starting place at Roma, that I'm a player who can help the team to do well and give my best."
Bradley has 69 caps for his country at the age of 24. His career has gone from strength to strength since moving to Italy following a disappointing spell at Aston Villa.
