Andy Murray will hope to take inspiration from Novak Djokovic and Stan Wawrinka for his must-win match against Milos Raonic at the ATP World Tour Finals.
The record for the most one-sided match since the tournament moved to London in 2009 was broken twice in one day on Monday.
First Wawrinka defeated Tomas Berdych 6-1 6-1 in 58 minutes, while – in the evening – defending champion Djokovic took two minutes fewer in beating US Open winner Marin Cilic by the same scoreline.
That put both men in a great position to reach the semi-finals, and a similar result for Murray against Raonic this evening would significantly boost his hopes of a last-four spot.
For that to happen Murray must find a much higher level of tennis than he managed in a meek defeat by Kei Nishikori in his opening match on Sunday.
“Obviously now I need to win my next two matches more than likely, and win them well if I want to go through,” said Murray.
“That’s going to be tricky because Milos obviously played fantastic last week in Paris, and Roger (Federer) always plays well at this event. So I’m definitely going to have to play better.”
Raonic lost his Group B opener to Federer in straight sets but has beaten Murray in three of their previous four meetings, most recently in Indian Wells in March.
The Canadian said: “It’s a completely different match.
“Things are going to be quite different than the first match. We both have more of an idea what we need to do different for the next round. It’s going to be about who adjusts better.”
The 23-year-old qualified for the eight-man event for the first time and admitted adjusting to the round-robin format is a challenge.
“I get pretty angry when I lose, so I’m going to have to learn how to slap myself out of it,” he said.
Federer and Nishikori meet in the afternoon, with the Swiss bidding to improve his chances of finishing the year as world number one with another victory.
If he could overhaul Djokovic, he would be the oldest year-end number one by a significant margin, but he knows the odds are not in his favour given the points differential.
Federer said: “The rankings came by surprise that all of a sudden I have a small shot at world number one after winning Shanghai.
“I’m happy it’s this way. But I think it’s highly unlikely it’s going to happen. If it does, obviously it’s great.
“But, for me personally, it doesn’t really matter if it happened at the end of the year or any other week during the year, as long as you could get back to world number one for one more time.
“I think that would be very special because I’ve been there and I know how much it would mean.”
