Queens Park Rangers' summer signing Anton Ferdinand is glad to have returned to London and also thanks Sunderland manager Steve Bruce for turning him "from a boy into a man".
Ferdinand had been involved in several bust-ups with Bruce during the two years the duo worked together at the Stadium of Light.
However, the 26-year-old appeared to have settled all differences with Bruce when he started the 2011-12 campaign as a first-choice defender but was still sold to QPR on transfer deadline day.
Ferdinand, though, has no regret over joining the Premier League newcomers and explained: "The last two years have been full of ups and downs, as everyone knows, with the manager at Sunderland.
"In some ways I have to thank him because he's turned me from a boy into a man. Coming back to London, it's a new me. I feel different to how I was when I left London four years ago, and I'm here to enjoy my football."
"I feel I haven't had the chance to prove my potential in the last couple of years," the Englishman further enthused. "That's a chapter that's closed in my book now and there's a new chapter open.
"Hopefully, I will get the opportunity to do it and, if I do, then I'm confident in my ability that I'll show people that I'm not just someone with potential, but someone who can carry out their potential."
