The 2026 tennis season is about to kick off in Melbourne, but for current world No.1 Carlos Alcaraz, the start of the new season is far from smooth. With the sudden departure of veteran coach Juan Carlos Ferrero and the strong resurgence of rival Jannik Sinner, Alcaraz’s top ranking is under unprecedented threat.

Australian Open: A dream venue and a battle to defend points
Alcaraz will head to the Australian Open with a clear goal—to complete the set of all four Grand Slam titles and officially join the “Career Grand Slam” legends. However, Melbourne Park has always been a weak point in his career, as he has never advanced beyond the quarterfinals there.
What troubles him even more is that to lift the trophy in Melbourne, he will very likely have to overcome the in-form Sinner. The Italian has been unstoppable in the Australian Open over the past two years, dominating the tournament en route to victory. For Alcaraz, reaching the final is not only about glory but also crucial ranking points to secure his precarious world No.1 status.
Ranking pressure: 2025’s success becomes 2026’s “debt”
In 2025, Alcaraz delivered dominant performances on both clay and hard courts, but this also means he faces enormous pressure to defend points in 2026.
February: He must defend his title at the Rotterdam ATP 500 event.
March: He needs to reach at least the semifinals at the Indian Wells Masters.
April-May: The champion points (1000 each) from Monte Carlo and Rome Masters will be deducted.

This series of “point defense pitfalls” means Alcaraz must sustain last year’s stellar form to maintain his current ranking. However, losing Ferrero, his mentor since junior days, has raised doubts about the stability of the six-time Grand Slam champion.
Sinner’s “point-grabbing” opportunity: Suspension absence turns into an advantage
The key variable changing the battle for world No.1 is Sinner.
Due to a doping suspension, Sinner missed three months of the previous season, skipping major Masters events like Indian Wells, Miami, and Monte Carlo in 2025. This means he has no points to defend during the same period in 2026, making every point he earns pure gain.

Sinner has the chance to amass up to 3000 points just from Indian Wells, Miami, and Monte Carlo alone, plus he can expand his lead further by competing in ATP 500 events. If Sinner maintains the dominance he showed this season, he could easily overtake Alcaraz in the first few months of the new year with a “lightning-fast” surge.

Can Alcaraz hold firm without Ferrero?
With Ferrero’s departure, Alcaraz has lost not only tactical guidance but also a psychological pillar. As commentators note, any fluctuations in form will be magnified.
The first half of 2026 will be a turning point in Alcaraz’s career. Will he prove that he can win titles without a coach amid adversity, or will the pressure of defending points and Sinner’s challenge cause him to collapse? The heat in Melbourne will witness it all.
