Novak Djokovic apologizes to Roger Federer and offers a heartfelt tribute to the former star

Novak Djokovic apologized to Roger Federer when he paid tribute to his former rival following his retirement from the Laver Cup. 

In the wake of Federer's final game on Friday evening, the world's No 7 played and took home his first match with Team Europe on Saturday,

then delivered a moving speech to his opponent as he apologized for the way he made him "tear up".

Federer's amazing career of just 24 years ended on Saturday morning at the Laver Cup in London and the champion of 103 titles 

said goodbye in professional tennis on the O2 Arena with his Team Europe and Team World colleagues by close by. 

The 41-year-old was crying as his retirement became reality and his family accompanied his on the court during the emotional ceremony.

Rafael Nadal already revealed his thoughts about his rival and friend's retirement, as he joined Federer in the doubles match for the Swiss tennis star's final match. 

Their fellow Big Three rival Djokovic has recently paid a touching thanks to Federer's 20 time Major champion, as he shared his thoughts about this "beautiful moment".
