Ivan Ljubicic has a keen interest in tennis and the Croatian revealed that Federer enjoys the game as well.
Roger Federer is a very competitive person which is what got him to the top of tennis in the first place. The Swiss player is a fan of many other sports besides tennis having played football at a very good level as a youngster.
His former coach Ivan Ljubicic revelaed his interest in chess in a recent interview as well:
"He likes to play kind of bullets to kill time and distract himself. I know more (than Roger) or less but I prefer not to talk about it. He would not enjoy me talking about it."
Bullet tennis is a fast-paced tennis format where players need to make quick decisions and live with the consequences. It's quite similar to tennis with Ljubicic revealing how Federer got into the game:
"He got hooked by seeing how fanatic I was about it. He had the basics and I honestly don't know if he still does it because we haven't spent a lot of time together in 14 months since he had surgery but yeah he also knows the general ideas of what's happening in the chess world."
