The world's two best tennis players, Rafael Nadal and Novak Djokovic, are already knocked out of the ATP playoffs in London.

Today, the World Tree Roger Federer was also eliminated.

The Swiss fell in straight sets, 6-3, 6-4, against the Greek Stefanos Tsitsipas, who is ready for his first Masters final of his career.

- Wow, I'm so proud of myself today. It was a good effort and I could really enjoy the plan. Roger played well today. It was tough. This is probably one of my best matches this season, says the Greek to Viasat Sport.

There is now either world fiancé Dominic Thiem, Austria, or world champion Alexander Zverev from Germany.

Tsitsipas played as late as yesterday a three-hour match against Rafael Nadal, where he lost.
