Swiss tennis great Roger Federer surprised a young fan, Izyan Ahmad, also known as Zizou. He flew to Zurich to fullfil a promise he made to him half a decade ago. During the US Open press conference five years ago, Zizou challenged Federer to a match.

Federer Instagrammed his meeting with Zizou recently and wrote: “One of the great benefits of this unbelievable sport are moments like these. Zizou, all the best and keep working hard. PS: I always keep my pinky promises.”
