(Reuters) - Novak Djokovic has shown that age is not a barrier and the 35-year-old will continue to break records, his younger rivals on the ATP tour said as the Serbian star looks to overtake Steffi Graf as the player with the most weeks at world number one.

Djokovic won a record-extending 10th Australian Open title last month to draw level with his great rival Rafa Nadal on 22 Grand Slam victories and leapfrog Carlos Alcaraz into top spot in the ATP rankings.
