Rafael Nadal announced his impending retirement from tennis on Thursday at age 38 after winning 22 Grand Slam singles titles during an unprecedented era he shared with his rivals in the so-called Big Three , Roger Federer and Novak Djokovic.

Nadal said he will retire after next months Davis Cup finals.

Really, everything I have experienced has been a dream come true, Nadal said in an announcement on social media. I leave with the absolute peace of mind of having given my best, of having made an effort in every way

The Spaniard indicated his decision was related to persistent injury problems.

The reality is that it has been some difficult years, these last two especially. I dont think I have been able to play without limitations. It is obviously a difficult decision, one that has taken me some time to make. But in this life, everything has a beginning and an end, Nadal said.
