Roger Federer had to hold back the tears as Laver Cup defeat alongside Rafael Nadal brought his illustrious career to an end but the 20-time Grand Slam winner insisted he was not sad. The 20-time grand-slam champion announced last week he would bow out from competitive tennis with one final match at the Ryder Cup-style competition which was his brainchild. London was the destination for the fifth edition of the Laver Cup, the city for some of Federer's greatest triumphs, but the Swiss superstar could not add one more victory to his illustrious CV.
