Wawrinka ready to take next step in London

US Open champion Stan Wawrinka is eager to top previous performances at the ATP World Tour Finals and reach the title match in London.

The world number three has qualified for his fourth successive tour finale after making the semi-finals on each of his previous three appearances at the O2 Arena.

But Wawrinka is eager to go further in this year’s tournament, with the 31-year-old getting his campaign underway against Kei Nishikori on Monday.

“This is an amazing tournament for every player. It was always a dream for me to play in this tournament, so to finish my year playing here is very enjoyable,” said Wawrinka.

“It was my goal at the beginning of the year to make it back, so I’m pleased to be here and I want to make the most of it.”

Wawrinka beat Nishikori in the semi-finals of the US Open, but is wary of the threat posed by the rising Japanese player.

“He’s a tough player,” said Wawrinka. “The conditions here are very fast, so it’s important for me to try and be aggressive, put a lot of pressure on him and push him back.

“I need to try to make it a physical battle."
