Serena Williams, who has said she is "evolving away from tennis" herself, has hailed retiring Roger Federer as an inspiration.

"You inspired millions of people, including me, and we will always remember you," said Williams.

"Welcome to the club!" Thank you for being who you are.

It will be the end of a career that featured 20 Grand Slam singles titles for the 41-year-old.

"I have looked up to you and respected you," said Williams. I look forward to everything you do in the future.

The only time they played against each other was in a mixed doubles match.

It's been a pleasure to watch you grow. I hope you have a good one.

Spaniard Alcaraz said thatRoger was one of his idols. We would like to thank you for everything you have done. I would like to play with you.

Sharing time/experiences on the most hallowed grounds was an honor. Don't be mean to other people.

I think it's a good time to start training for Wimby.
