Watch Djokovic vs Berdych and Wawrinka vs Cilic Live Online: ATP World Tour Finals Day 6 Live Streaming Information

Novak Djokovic and Tomas Berdych will take on each other while Stan Wawrinka will face Marin Cilic, in the final round robin matches on Day 6 of the ATP World Tour Finals at the O2 Arena in London on Friday.

Both Djokovic and Berdych had posted wins in Group A on Wednesday. The world number one followed up his victory over Cilic on Day 2, with a 6-3, 6-0 win over Wawrinka.

Berdych, on the other hand, bounced back from the opening match defeat to Wawrinka, to see off the challenge from Cilic 6-3, 6-1.

Defending champion Djokovic has had a good season on the tour this time. He won the Wimbledon, regained the world no.1 rank and collected six titles overall this year, with an impressive 57-8 record. The 27-year-old is now a favourite to end the year atop the ATP rankings, though world no.2 Roger Federer is only a few points away from usurping him.

The Serb has been happy with his performances so far in the Tour Finals, especially Wednesday's comprehensive win over Wawrinka.

"I definitely didn't expect it, but hoped that I can play this way again and the match result can go this way for me. Obviously Stan wasn't feeling his best, made a lot of unforced errors and had a low percentage of first serves in," Djokovic said after beating the Swiss.

"On my side, I just played very solid from all over the court. I think I covered the court very well, got a lot of balls back, mixed up the pace, got him off the comfort zone. That's something that was part of my game plan."

Berdych, meanwhile, had yet another decent season. The Czech had gotten off to a good start by reaching the Australian Open semifinal, and though he failed to better that in the following Grand Slams, he produced good shows in the Masters events.

The world no.7 suffered a 6-1, 6-1 loss to Wawrinka in his opening match in the Tour Finals but came back with a convincing win over Cilic on Day 4.

"I felt much better on the court. But still it was not one of my best. That's fair to say. But I think that's the beauty of this event. One day you can be swept out from the court like I did and in two days' time you can come up and you can play a different tennis," Berdych pointed out.

Djokovic leads the head-to-head record against Berdych 15-2, and had beaten the Czech 6-2, 6-0 in the China Open final last month.
