Tennis fans spent years watching Novak Djokovic, Rafael Nadal, and Roger Federer dominate the sport, as the thought of anyone else on top became unthinkable.
Sinner won the Australian Open in January before picking up his second Major at the US Open in September, claiming the world number one ranking in the process.
On the other hand Alcaraz won the French Open and Wimbledon titles, as he took his Grand Slam tally to four.
It looked like a real ‘changing of the guard’ moment, but even if Alcaraz and Sinner were to dominate the sport for the coming years, just how long would it take them to steal the ‘big three’s’ most unbeatable records?
Starting with a record that most tennis fans agree will remain untouched, is Nadal’s 14 titles at Roland Garros.
An astonishing number that only becomes harder to believe the more you think about it.
Alcaraz got off the mark this year with his win against Alexander Zverev but still has a long way to go if he wants to take the record from his countryman.
