Novak Djokovic made an ­impressive return after two months out of action as the Team Europe star thrashed Frances ­Tiafoe 6-1, 6-3 with Roger Federer cheering him on at the Laver Cup on Saturday.

Djokovic showed no signs of rust in his first appearance since winning the seventh Wimbledon crown of his remarkable career in July.

The 35-year-old followed his dominant victory over Tiafoe at London's O2 Arena with another win just hours later alongside Matteo Berrettini in the doubles.

Djokovic and Berrettini beat Jack Sock and Alex de Minaur 7-5, 6-2 to put Team Europe 8-4 up heading in the final round of matches on Sunday.

Djokovic, a 21-time Grand Slam champion, missed the US Open in September due to his unvaccinated status, leaving him to take an enforced break from competitive action.

But he was quickly back in the old routine against Tiafoe as he broke in the fourth game and again in the sixth to take the opening set in just 23 minutes.

Djokovic cruised through the second set, with Federer and the rest of the Team Europe squad gathering at courtside to congratulate him.

Federer said a tearful goodbye to tennis late on Friday night when the 20-time Grand Slam champion and doubles partner Rafael Nadal were beaten by Tiafoe and Sock.

The 41-year-old announced earlier in September that he would retire after the Laver Cup due to the knee problems that had kept him on the sidelines since Wimbledon in 2021.

Federer's departure from tennis has raised the question of retirement of the other two members of the revered "Big Three" but Djokovic has assured that he does not feel "old enough" to consider bringing down the curtain yet.

Federer's exit has brought the longevity of his great rivals, Nadal and Djokovic, in sharper focus while fans and pundits have wondered how men's tennis would cope with the prospect of losing their most marketable athletes.

"I don't feel yet so old, to be honest, for my tennis career to finish," Djokovic told reporters on Saturday.

"I still feel my body is serving me, is listening to me well. That's the key I think when you get to 35-plus.

"We knew it would be an emotional farewell for Roger but we were all taken away by the m oment. I think we would all agree this was one of the most beautiful moments anyone has experienced on a tennis court.

"It's mixed emotions. Sadness because one of the greatest athletes of all time is leaving the sport, but on the other hand seeing him happy with the way it all played out."

Federer's fitness issues meant he could only play one doubles match, so Berrettini was called into the Team ­Europe squad to replace the Swiss legend after the last act of his incredible career.

Relaxed Federer

Berrettini proved a capable deputy as he defeated Felix Auger-Aliassime 7-6 (13/11), 4-6, 10/7 in Saturday's first match.

The 26-year-old Italian, who finished as the 2021 Wimbledon runner-up, had to dig deep to hold off a spirited challenge from Auger-Aliassime, a 22-year-old Canadian rising star.

On the first day of his life after ­tennis, Federer could have been forgiven for following Nadal's example and heading off for a well-earned rest.

But Federer showed his passion for tennis is unlikely to fade anytime soon as he sat courtside to support Berrettini despite the post-midnight finish to his emotional finale.

Federer, who was involved in ­setting up the Ryder Cup-style ­Laver ­tournament, looked relaxed and refreshed as he mimicked Berrettini's clenched-fist celebration during the Italian's victory.

"I'm really happy for the win, but this weekend we're celebrating something bigger than Laver Cup. It's just about him [Federer]," Berrettini said.

In the day's second singles match, Team World's Taylor Fritz beat British world No.8 Cameron Norrie 6-1, 4-6, 10/8.

Norrie was only playing because Nadal had opted to pull out of the rest of the tournament after the Federer doubles match for what organizers said were "personal reasons."

The Spanish world No.3 has been struggling with an abdominal injury while his wife is heavily pregnant.
