(Reuters) - Novak Djokovic turns 37 next year but the Serbian says his appetite for success will only increase with young challengers awakening the "beast" in him.

The world number one enjoyed an extraordinary 2023 by winning three out of the four Grand Slams to take his tally to 24, two more than his great rival Rafa Nadal and four more than the retired Roger Federer.
