Roger Federer clearly had plenty of gas left in the tank after his straight-sets Wimbledon final victory, with the Swiss maestro embarking on a huge night out in London to celebrate.

The 35-year-old father of four – who cruised past an injury-affected Marin Cilic to win Wimbledon for a record eighth time – left no stone unturned in his bid to mark the achievement.

Federer partied until 5am after claiming the 19th grand slam title of his singles career, starting his evening at the traditional post-event ball before ending up at a bar – where he claims he doesn’t know what he did.

“My head is ringing,” Federer candidly told a press conference on Monday [UK time].

“I don’t know what I did last night. I drank too many different types of drinks, I guess.

“But after the ball, we went to a bar and there was about 30 or 40 friends there.

“We had a great time. I got to bed at five and I woke up and I didn’t feel good.”

Federer said that despite his big night, he did not take part in the traditional dance with the winner of the women’s singles tournament – Spaniard Garbiñe Muguruza – at the ball.

“When there’s no music whatsoever, it’s hard to get going,” he added, in relaxed fashion.

When pressed on his future, Federer acknowledged that he had already thought extensively about his plans for 2018.

And the good news for sports fans is that retirement is not even a consideration of Federer’s.

“Honestly, ever since I had the year I had last year [severely injury interrupted], I do think probably like a year ahead of time with my schedule, fitness schedule, tournaments I would like to play,” he said.

“So I totally see myself playing here [Wimbledon] this time next year.

“But because it’s far away, because of what happened last year, I just like to take the opportunity to thank the people in the very moment, and make them understand, yes, I hope that I’m back.

“[But] there’s never a guarantee, especially not at 35, 36.”

Federer has belied his age to win five of the seven tournaments he has entered in 2017.

The last grand slam of the tennis season is the US Open, which begins in New York on August 28. Federer is already the tournament favourite.
