Roger Federer sent tennis fans around the world into a frenzy on Tuesday when he answered questions on Twitter.

Naturally, some fans asked about Federer’s rivalry with Rafael Nadal. Does the Swiss miss playing the Spaniard?

yes and no 😉

Federer and Nadal played many memorable matches that will be spoken about for years to come. Which was the 20-time major winner’s favourite?

RG 2008. Those 4 games were awesome. 😉

That was a joke from Federer. The 2008 Roland Garros final was one of the most lopsided matches in their legendary ATP Head2Head rivalry. Nadal won 6-1, 6-3, 6-0.

Perhaps the bigger surprise was the answer Federer gave when asked about any funny stories he has of being mistaken for someone else.

happened the other day at the Formula 1. A guy asked "Can i have a picture with you Mr Nadal?". I told him I wasn't Mr Nadal. He apologized and left without taking a picture. 😂

Federer won 1,251 tour-level matches and 103 titles, so it was no shock fans picked the Swiss’ tennis brain for advice.

in tennis, there is so much you always want to improve. there are so many incredible details. you have to be selective and methodical in how you go about it. a great coach helps you prioritize what to work on in what order, and what the end goal should be over the next 1/3/5…

overcoming adversity. not dwelling on the past. staying creative and thinking out of the box. all of these were important skills as a tennis player but feel just as relevant today.

You have to surround yourself with the right people and listen and learn quick.

just gotta keep moving on. can't dwell on it. learn and take the positives.. there's always something there.

Although Federer is enjoying his routines at home and time with family, he explained why he misses tennis.

in a crazy way, i miss everything about it. for years of my life i didn't even remember what day of the week it was (other than Monday was the start of a tournament and Sunday was the end).

people still send them to me (mostly my dad) so yes sometimes

There was a lot of little stuff that i didn't know was creating so much stress that just dropped away, which is really cool. Like a weight being lifted off my shoulders.

— Roger Federer (@rogerfederer) May 23, 2023

feeling great nowadays, thanks! what i miss most: having a spontaneous dinner out on tour with friends after a match or practice. and of course the big stadiums, fans and the thrill of it all.

Even in retirement, his sense of humour is as good as ever. He listed the best servers and included 5'7" Diego Schwartzman.

Roddick/Isner/Pistol/Schwartzman/Karlovic/Ivanisevic/Raonic/Vavrinec. And some bald guy from Croatia @theljubicic

One of Federer's coaches, Ivan Ljubicic got in on the Q&A action and received a joke in return.

Give me a few hours to go through the history books and i'll get back to you

— Roger Federer (@rogerfederer) May 23, 2023

One fan asked Federer when he is coming back.

i never really left
