Serena Williams and Roger Federer don’t completely convince John McEnroe

For John McEnroe, it may not be over

It takes John McEnroe to open an interesting debate on the farewell to tennis of Serena Williams and Roger Federer, two who have made history in world sports.

“Serena Williams and Roger Federer are tennis legends and as such ‘they can do what they want.’ For me, if you announce retirement, you have to retire, however, other champions have come back saying, ‘Hey, I played well, I can still win!’ I mean, any other eventual decision will be up to them alone. Roger and Serena seem to me to be ready to move on, however, tennis is such an important part of their lives that you never know–and we certainly wouldn’t blame them. In fact, we would like to see them play forever, but if they believed that ‘This is how it has to end,’ then it will be better for everyone,” the former racquet champion tells Discovery.
