Serena Williams' childhood coach Rick Macci called Roger Federer "a poetry in motion" and identified the Swiss' movement as one of his biggest strengths. Federer, a former 20-time Grand Slam champion, made tennis look easy as many agree that the Swiss' tennis is the most aesthetically pleasing in the game's history.

"Let's talk a little bit about the great Roger Federer. Poetry in motion, amazing forehand technique, one of the best backhand slices of all time, his serve biomechanically was amazing. But I need everybody to understand that when you see someone at this level, the movement is the wildcard.

He's like going on eggshells and floating around the court," Macci said in a video uploaded on his social media, via Sportskeeda.

After struggling with knee injuries for a few years, Federer announced last September that his final tournament would come at the 2022 Laver Cup.

In what was the final match of his career, Federer teamed up with Rafael Nadal for a doubles match at the Laver Cup. This week, Federer took part in a Q&A session on Instagram. Expectedly, Federer was asked about how retirement life has been going.

"What are you enjoying most since retiring from professional tennis? What do you miss the most?" a fan asked Federer during the Swiss' Q&A session on Twitter. Federer replied: "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." Since retiring, Federer hasn't made any appearances as a guest in tournaments. During the same Q&A session, Federer was asked if he was planning to be a guest at this year's Laver Cup in Vancouver. Answering to the fan, Federer revealed that he is going to be at the Laver Cup later this year.
