Swiss tennis star Roger Federer was nearly perfect at the ATP World Tour Finals, beating Novak Djokovic 6-1, 6-4 on Saturday evening in the semifinals.

The second-ranked Swiss will now meet Spaniard Rafael Nadal in the final in London later on Sunday - in what is an eagerly awaited match.

"I was able to outplay him at times, play aggressive. I took it to him, exactly the way I was hoping to make it," Federer said.

Federer's play appeared effortless, just as it did in the mid-2000s when he won more than a dozen major titles.

"He's really stepping in, hitting the backhands and forehands all over the court, winners. Every ball kind of listens to him," Djokovic said. "It's very hard. He doesn't give you a lot of free points."

Nadal, the world number one, beat Britain's Andy Murray 7-6, 3-6, 7-6 in an epic match on Saturday afternoon.

"Obviously I'm really looking forward to playing against Rafa. Who wouldn't?" said Federer.
