Rafael Nadal has already locked his place in the semifinals of the ATP World Tour Finals as well as top spot in the Ilie Nastasic Group, and now the Spaniard will target a clean sweep of the round robin stage of the tournament in London when he plays compatriot David Ferrer on Friday at the O2 Arena.

Nadal picked up two impressive wins over Stanislas Wawrinka and Andy Murray in his opening two matches to ease his way into the semifinals, where he will meet the world number one Novak Djokovic.

The perfect way to prepare for that mega match is by keeping the winning momentum going, which a victory over Ferrer will achieve.

Nadal, who has had a difficult 2015, failing to win a single Grand Slam, will want to keep that serve, forehand and backhand of his working like a charm against Ferrer, much like it did against Murray on Wednesday, when the Spaniard came away with a 6-4, 6-1 win.

"It is an important victory, because it puts me in a good position for the semifinals, and at the same time I have had a big day against a great player on a tough surface," Nadal said after his win over the Brit.

"I'm just happy the way that I played, happy the way I was working. Just another step for me to be able to play at that level, against such a great player, is good news. Happy for that.

"Just want to try to keep working the same way to keep confirming that I am completely in the right direction."

Ferrer is already out of the ATP World Tour Finals, having lost his first two matches. The other semifinal spot will go to the winner of the later match between Murray and Wawrinka. However, even if he no longer has an opportunity to qualify for the semifinals, Ferrer will want to bow out of London on a high, and as a result Nadal will have to bring his top game again, if he is to finish the group stages unbeaten.
