Klitschko announces retirement from boxing

A statement from the former world champion read: "I deliberately took a few weeks to make my decision, to make sure I had enough distance from the fight at Wembley Stadium.

"As an amateur and a professional boxer, I have achieved everything I dreamed of, and now I want to start my second career after sports.

"I would have never imagined that I would have such a long and incredibly successful boxing career. I'm very thankful for this. Thanks to everyone who has always supported me, especially my family, my team and my many fans."
