Roger Federer continues to keep a keen eye on tennis despite retiring from the sport at the 2022 Laver Cup.

Federer called time on his glittering career at the London event three years ago, with the Swiss star now back at the Laver Cup this week.

The latest edition of the tournament is currently underway in San Francisco, while it makes a return to London next year.

Federer caught up with Joao Fonseca at this year’s competition, although the Brazilian youngster is representing Team World, while the Swiss legend represented Team Europe.

The veteran made four appearances at the Laver Cup, claiming 18 points for his side from his 12 matches played.

He’s now in a spectator role at San Francisco’s Chase Center, although Federer has been fine-tuning his tennis game behind the scenes.

The 103-time ATP champion told Tennis Channel: “I’m trying to be in good shape. I played a ton of golf. That was also the time to give my knee a good rest.

“And now I’m trying to play [tennis] like two or three times a week, get back on the court and also play some points and all that, just to get the feel for it.

“And the good thing is I’ve always served every time I go on court with my children, I try to hit some serves, because that thing gets really rusty quickly. “But I must say, I think I’m actually feeling pretty good. I’m really happy three years later that my body is still as good as it is.

“And I think now I can really start feeling the benefits of having given it a break, because the first couple of years right after retiring was tough.”

Roger Federer explains why life after tennis retirement is ‘good and bad’

Federer delved further into retirement life, which has proven to be bittersweet thus far for the 20-time Grand Slam champion.

He explained: “Well I miss the camaraderie. So actually in a week like here when I’m in and out of the locker room, I just got into the locker room before with Pat [Rafter] and Andre [Agassi], and they say ‘come sit down now, we need to talk to you for a second.’

“And I sit down and we have a quick banter chat for like five minutes. That’s what I miss the most. Sure, you miss the two minutes where it says game, set and match Federer and you win Wimbledon, and you’re like, ‘okay that’s kind of cool’.

“But it kind of evaporates really quickly. So I think it’s just life on the road and seeing my friends, going to dinners and just hanging out on the road.

“I think I miss that. And life in retirement is great. I don’t have to train through a practice when I’m not feeling great.

“I don’t have to play a match when my body’s aching, so it’s good and bad, but I, of course, miss many things.”

While Federer may not always miss tennis, it’s fair to say that tennis misses him, although it seems that his on-court endeavours may not be finished just yet.

There is a potential Federer comeback on the cards, which would simply send all tennis fans into a frenzy.

He would be welcomed back onto the court with open arms, and given how often he’s currently playing, it’s fair to say he would still be a formidable opponent even at the age of 44.
