Roger Federer played plus 1,400 matches as a professional singles player since 1997 but he still loves tennis and he plans to play it also after he ends his career. Federer rarely suffered major injuries during his career, except the knee in 2016.

And so that's why he may compete in Laver Cup as an effective player once his career ends. 'I see myself going to an event like this and having just a cool three days without working with friends', said Federer, who is one of the Laver Cup co-founders and investors. 'I know a lot of retired tennis players don't see themselves doing that.

They feel, oh, what am I doing? People will only come up and talk to me. But maybe I would like to watch great tennis with a great team spirit and laugh about what the teams are doing, enjoy great tennis. Of course I hope I will be involved in some shape or form, but at the same time it's not something I plan for.

This is more something for legends and legends down the road that everybody can connect here and have a great time. That was the idea behind it. I'm sad to hear they don't care if I play or I don't play, you know, because I hope they only want me to play every time forever.

No, all kidding aside, it's great being part of the team, and I'm a bit sad today that -- I wanted to be undefeated forever at the Laver Cup, and today unfortunately that happened. But it's all good. I will try to pick myself up for tomorrow.

It's a great weekend again, and we are having really a great time as a team. And it's so much fun having Novak this time on Team Europe.' ALSO READ: 'Roger Federer should never play on clay again' - Andy Roddick
