"I'm not sure Rafa will be this upset at his own retirement" - tennis fans reacting to emotional Nadal at Federer's retirement

Roger Federer retired from tennis last night and Rafael Nadal was shaken up during the ceremony as he cried through much of it.

Rafael Nadal and Roger Federer share a special kind of rivalry, one that is not seen often in the world of sports or in tennis. It was on full display during Federer's retirement ceremony last night in London as Nadal could not fight off his tears matching Federer in that department.

Rennae Stubbs wrote:

"A moment in sporting history I can't and won't ever forget. Have we ever seen anything like that. His greatest rival crying because he'll never play with or against him again. Rafa, man you are a Champion. Roger thank you for making this sport."

Some other fans added:

"These are not the tears of tennis legends, but these are the tears of tennis."

"I'm not sure Rafa will be this upset at his own retirement."

"If you saw the way Nadal cried all the way through Federer's farewell, you were witness to something that has never been seen before.Your biggest rival, bawling his eyes out at your retirement? The stuff of movies. Of folklore. It just isnt supposed to happen.And yet it did."
