Preview

Stanislas Wawrinka must beat the already eliminated David Ferrer to stand any chance of reaching the semi-final on his ATP World Tour finals debut.

The Swiss' damaging straight sets loss to Rafael Nadal, and Tomas Berdych's win over Ferrer on Wednesday means Wawrinka has no margin for error against a player against whom he has a 4-7 win-loss record.

Wawrinka did however win the pair's last meeting, on the clay at Oeiras and finds the world No.3 in poor physical condition after his exit following two defeats without winning a set.

Should Wawrinka win then Berdych will be required to beat Nadal, who will finish 2013 as world No.1, to reach the last four.

Nadal has won the last 15 meetings between the two, with Berdych's last win coming in Madrid in 2006, one of three hard court wins against the current French and US Open champion.

What they said

David Ferrer: "I didn't arrive here in good physical condition I made a lot of mistake an this is not the best version of David Ferrer. Physically I am exhausted. I am please for Nadal, he has put in a fantastic season."

Stanislas Wawrinka: "It's all about me the next one. I'm really positive and really happy with my level. I'm really confident in myself. I just know against a player like Ferrer, it's not only about myself."

Rafael Nadal: "I am very far away from winning this title. Here we are fighting. Winning two matches already, that's a very positive thing for me."

Tomas Berdych: "It's going to be a big one, that's for sure. Now I'm going to fight to go through for the semi-finals. I probably cannot have any tougher opponent than I have. But he's already through. He's secure for No. 1. You never know."
