"The Greatest Of All Time": Roger Federer Announces Retirement, Here's How The World Reacted

Tennis legend Roger Federer, in an emotional note, announced his retirement on Thursday. The winner of 20 Grand Slams admitted that his battles with a knee problem had forced him to call time on his historic career. He will play his final match on The Tour in next week's Laver Cup. The 41-year-old winner of 20 Grand Slam titles has been out of action since a quarter-final loss at Wimbledon in 2021, after which he underwent his third knee surgery in 18 months.
