Former Torino striker Rolando Bianchi feels he let himself down at Manchester City.
Bianchi is currently with Atalanta, having joined City six years ago.
"I reckon that in Manchester I could have done something more," Bianchi told Sky Sport Italia.
"I chose to come back to Italy because of the national team. But I think that if I had stayed [in Manchester] I could have done something important.
"When I was young I didn't think I'd have such a career but now probably I think that I could have done something more.
"In any case, it's never easy, and I am already happy to have done what I have done."
