At the press conference following his defeat, Djokovic said something interesting that jumped out: “What doesn't kill you makes you stronger, I guess. I need to have that kind of mentality and move on. I'm still young, and hopefully I have more opportunities to win this title.”
This quote straightaway reminded me of Metallica's "Broken, Beat & Scarred." In fact, this song perfectly sums up Djokovic as a tennis player. He is the most relentless tennis player I've ever seen on the court. He never gives up, and never gives in, and fight to the final breath.
