Roger Federer has revealed how his career-threatening injury changed his approach to the game

LESS has become more for world No. 2 Roger Federer as he attempts to extend his dazzling career beyond 2018.

Federer remains a giant of the sport at age 36, winning two grand slam titles in a dream 2017, including the Australian Open.

But after spending most of 2016 on the sidelines with a career-threatening knee injury, Federer knows he needs to take it easy with his body. Federer injured his knee while running a bath for his twins, and he knows he might be just one more serious injury away from having his career ended. But for the moment he has no thoughts of retirement.

Instead, he is eyeing off more grand slam success, and he believes the key to achieving that is by training smarter, instead of harder.

“Through the injury I sustained here in Australia a couple of years ago, my mindset has changed,” Federer said.
