If Jannik Sinner retired tomorrow, he would still have enjoyed a legendary career that most could only dream of.
Instead, the 24-year-old still has so much time left to add to his already-sparkling legacy, which already consists of four major titles and a further eight Masters 1000 events won.
However, as records continue to fall in his wake, there is one potential feat which he is still on track to achieve this year.
If he were to manage it, it would see Jannik Sinner complete what could arguably be branded the toughest achievement in tennis.
Jannik Sinner could win all nine Masters 1000 events this year
Whilst it is a near-impossible task that no man or woman has ever managed before, it seems hard to bet against Sinner at the moment.
As such, he very conceivably could become the first player in history to win all nine Masters 1000 events in a single year.
Who would win this legendary showdown?
Having just reached the final in Madrid, and already won the first three tournaments at this level of this season, the world number one is already nearly halfway there.
With Carlos Alcaraz having already withdrawn from Rome and Roland Garros, Sinner should claim that Masters 1000 title as well, before the tour then heads to his favoured hard courts again after Wimbledon.
The 24-year-old has already won the Canadian Open, Cincinnati Open, Shanghai Masters and the Paris Masters.
Sinner is well and truly on track to create sporting immortality this year, and it feels like everything is falling into place for him.
Who has come closest to winning all nine Masters 1000 events in the same year?
It should come as no surprise that Novak Djokovic is the man who holds the record for most Masters 1000 titles in a single year, and therefore came the closest to winning them all in the same campaign.
However, even he did not manage to go as far as Sinner has so far, currently unbeaten as we head into May.
Back in 2015, the 24-time Grand Slam champion kick-started his campaign by winning the Sunshine Double, just after he had clinched yet another Australian Open.
Then, winning Monte Carlo, there was surely a genuine belief that Djokovic could do the unthinkable and win all nine Masters 1000 events in that season.
Alas, he clearly had other priorities, pulling out of the Madrid Open to prioritise Rome, which he won.
| Event | Result |
| Indian Wells | Winner |
| Miami Open | Winner |
| Monte Carlo Masters | Winner |
| Madrid Open | Second round |
| Italian Open | Winner |
| Canadian Open | Final |
| Cincinnati Open | Final |
| Shanghai Masters | Winner |
| Paris Masters | Winner |
He later lost in the final of both the Canadian and Cincinnati Open, before ending the year with titles in Shanghai and Paris.
As such, Djokovic finished 2015 having won six Masters 1000 events and reached a further two finals.
