Tennis great Roger Federer of Switzerland is all set to retire from professional tennis later this week. He will participate in the 2022 Laver Cup, starting this Friday, at the O2 Arena in London, where he will be teaming up for Team Europe against Team World. However, it is unclear if the 20-time Grand Slam champion will be featured in the singles matches. It would mark his first competitive tennis tournament in over a year, as he is coming off after nursing a knee injury and multiple surgeries. While fans are desperate to see him in action for the last time, he has expressed his desire to play the doubles alongside Rafael Nadal of Spain.
