Tennis star Novak Djokovic believes he is "the best" and that his belief and confidence in his own abilities has played a major role in his success.
Djokovic has won a record 22 Grand Slam men's singles titles, more than any other tennis player in history besides rival Rafael Nadal who has also won 22. And with Djokovic looking to overtake Nadal in 2023, he has opened up about his mindset.
Ahead of becoming the all-time leading NBA point scorer, basketball legend LeBron James said: "I feel like I'm the best basketball player that ever played the game. That's just my confidence, that's just what I bring to the table, what I possess."
