Stanislas Wawrinka and Marin Cilic will seek to reignite their challenge at the ATP World Tour Finals when they meet in the second match on day four at The O2 Arena.
Where to watch live
Wawrinka vs Cilic starts at 8pm GMT on Wednesday (16 November) and is live on Sky Sports 2HD and BBC Radio Five Live sports extra.
Stanislas Wawrinka or Marin Cilic face a possible early exit from the ATP World Tour Finals when they meet at The O2 Arena in London. The pair each lost their opening round robin match in straight sets and are just another defeat away from bidding an early farewell to the season-ending tour finals.
Wawrinka produced a listless display indicative of his recent run in his two-set loss to Kei Nishikori. The Swiss only showed rare glimpses of the form which sees him defend his world number three ranking this week and he was a clear second best as Nishikori powered to victory.
One positive for the US Open champion is his previous powers of recovery. He lost his first group match to Rafael Nadal in emphatic fashion 12 months ago, but rallied to reach the semi-finals for a third year in a row with wins over David Ferrer and Andy Murray.
Cilic produced a contrasting display in his loss to Murray on day two, with the Croatian pushing the new world number one all the way during an engrossing contest. Nevertheless, the world number seven was unable to rise to Murray's level and was left behind in the second set.
The 2014 US Open champion must currently juggle competing in London with preparing for Croatia's Davis Cup final with Argentina, and that may prove a crucial distraction against Wawrinka. Neither player can afford to crumble wondering after one-sided opening losses, meaning the contest could develop into a pure stroke-play shootout.
Six wins in a row against Cilic stretching back to the 2010 Australia Open does at least ensure Wawrinka enters the match as the slight favourite. However, having looked disengaged during the match with Nishikori there are questions over his mental state, not least his physical shortcomings.
What the players say
Stanislas Wawrinka: "I was feeling better on the court, so I thought I could play at a better level today. I was expecting a good match. Didn't happen today. Not the first time that I lose the first match here. Last year I lost against Rafa, really bad match. I'm sure I still have something inside me to play some great tennis before the end of the year, so I'm going to try everything for that in the next match. I'm going to do what I need to do tomorrow to get ready for trying to play better in two days.
Marin Cilic: "Obviously it is tougher to start straightaway with matches like these against the best guys. I'm not so used to it. That's something I guess quite new for me. Most of the tournaments I'm playing them third, fourth round at least. It's a little bit different to start straightaway in the match.
"But I'm quite positive with the way I was playing. Just saying it could have been some better decisions. It's the first match. You have to start obviously straightaway with good tennis. You don't have too many opportunities in matches like this.
"I had several opportunities, you know, to come back in the first set, or in the beginning of the second to maybe get advantage. Few opportunities you have, and if you don't make them, the score can be like this. I'm just saying overall I would need to obviously get a little bit more used to starting the matches, you know, like playing the best guys."
