Swiss tennis great Roger Federer, who has four kids with wife Mirka — two sets of twins — Myla and Charlene, nine and Leo and Lenny, four — has no plans to have any more children any time soon. In a recent interview with Swiss weekly newspaper, Coopzeitung, when Federer was asked if he planned to have more kids, he replied, "This topic is certainly not yet complete, but we are not going to deal with it until I have finished my career. That is why it is currently as good as it is. All are happy and relaxed. We enjoy the time with our four children."

Federer said his kids enjoy watching him play and that's a big motivation for him. "They know I play a lot of tennis, but I'm not sure if they know what my ranking is. But they know that there is a trophy involved at some point if I do play well because they get most excited about the trophies. I believe that probably it would take a few more years for the boys to really remember, anything" added Federer.
