The 2012 London Games succeeded in refreshing the Olympic brand by injecting enthusiasm as organizers delivered on their promise to create an event tailor-made for athletes, Jacques Rogge said on Sunday.

Hours before the flame was extinguished at the stadium's cauldron during the Games closing ceremony, International Olympic Committee president Rogge said he was a happy man.

"I am a happy and grateful man. On July 6, 2005, London promised athletes' Games and that is exactly what we got," said Rogge, who presided over his last Games, sitting next to London Games chief Sebastian Coe.
