Swiss tennis legend Roger Federer, who last week announced his imminent retirement wants to remain connected to "the sport that has given me everything," he said in an interview published on Tuesday. Federer, a winner of 20 Grand Slam titles and one of the best players of all time, sparked a global outpouring of emotional reactions when he announced he would retire after this week's Laver Cup. Last Thursday he admitted on social media that his battles with a knee problem had forced him to call time on a historic career that had earned him a reputation as one of the most elegant players the game has ever seen.
