Serena Williams welcomes Roger Federer to 'retirement club'

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.

In front of a crowd of more than 12,000, the Swiss duo of Roger and Bencic defeated the Americans.

There has been a wave of tributes to the tennis player after he decided to retire.

One of the two men's players with more Grand Slam singles titles said it was a sad day for sport.

Carlos Alcaraz and Iga Swiatek are the current world number one and number two respectively.

Pole Swiatek wanted to thank him for everything he's done for the sport.

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.

Andy Roddick joked that he'd launch an All England Club if he lost to him again.

The American thanked his friend.

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.

The legends of other sports were brought up.

Lionel Messi said that he was a genius.

He said that he was a role model for any sportsman.

We will miss seeing you on the court.

A regular in Wimbledon's Royal Box, the Indian cricket legend said that he was attracted to the style of the tennis played by the Swiss player.

He said it was a great career. We loved your brand of tennis. Slowly, you began to play tennis. Habit becomes a part of us.
