Roger Federer was front and centre last weekend as the Laver Cup took place in San Francisco.
Federer spoke to Joao Fonseca to give him some advice, as he was present at the event that he helped to create.
Interestingly, Federer often gets asked how much he plays tennis, and some intriguing claims came to light during the Laver Cup.
There has been talk of a senior tour featuring Federer and Nadal, and naturally, that has raised the excitement levels among tennis fans.
Now, a former top player has made a claim about Federer that should get the excitement flowing tenfold.

Mark Knowles shares what Roger Federer has told him about his fitness
Knowles is a former number one doubles player, and he recently took a place on the Inside-In podcast.
He was quizzed on Federer, and it would appear that he’s been updated by the man himself on how he feels about making a return of sorts to tennis.
Knowles said: “Every time I see him he looks better and better! More fit. It’s great to see him looking so fit. I have talked to him occasionally over the last two years or so, and he says everything is feeling great. He is spending a lot of time with his kids and family, and getting to see.
“He says he is truly getting to enjoy life, which he truly deserves, and I am glad his body is allowing him to.
“I’m sure being around tennis is getting the juices flowing, and I’m sure he’s hitting the ball as cleanly as ever. That would be pretty cool, right? A little Federer and Nadal senior tour!”
Seniors tour featuring Federer and Nadal would be quality
It’s fair to say that if people are going to part with hard-earned cash to watch tennis, Federer and Nadal would still be right at the top of the list for some people.
There is a lot of tennis to consume with the tour so packed these days, but if Federer and Nadal could find time to do something, that would be extremely exciting for fans.
Nadal hasn’t even been retired for 12 months yet, so he will still almost certainly be in good shape, whilst it appears Federer is keen to still play a bit.
Fans want excitement when it comes to sport, and there is no doubt at all whether Nadal and Federer taking to a court again would sell tickets across the world.
