Martina Hingis was one among the several players who praised Roger Federer after he became the world no. 1 for the fourth time in his career. Hingis, who retired from tennis after the WTA Finals in 2017, thinks that Federer's ability to evolve along with the game has been one of the reasons why he is still competitive after spending nearly two decades on the Tour.
'No one adapted their tennis as well as Roger, no one prepares for the game as professionally as he does. This is the secret of his success because he is a step ahead than all the other players,' she said.
Adding that his 'immense knowledge of the game' helped him compensate against his younger rivals, she noted, 'Roger Federer is the living lesson of this sport.' ALSO READ: Best Ad ever? Nike pays tribute to Roger Federer .
