Carlos Alcaraz and Jannik Sinner face the great challenge of continuing to consolidate an unquestionable duopoly at the top of the world tennis. The 2026 Australian Open stands as a golden test to continue demonstrating that the dominant trend of 2025 will also continue this season, with the incredible possibility of completing a poker of Grand Slam finals played between them (we have just witnessed the same showdown at Roland Garros, Wimbledon, and the US Open; only the Oceanic tournament remains).

Along the way, however, they will face feared challenges that could jeopardize their candidacies. As difficult as it may seem to envision a different final, the draw of the first Grand Slam of the year could be absolutely littered, with a large number of dark horses waiting from early rounds and fast-court specialists promising to cause problems, especially in the initial days of the tournament, maybe with some top contenders still a bit rusty. Jannik and Carlos will not cross paths until the final... and until that moment, creating a draw full of great challenges is our mission.

Alcaraz and Sinner must be careful in the first and second rounds, with Grand Slam finalists and Masters 1000 champions threatening in their debuts

Any player beyond #33 in the list could face Carlos and Jannik in the first round. This opens the door to real tough opponents who promise to make things very challenging from the start. The opponent to avoid clearly seems to be Hubert Hurkacz: his return to the circuit, after six months on the sidelines, has been devastating, crushing names like Zverev or Fritz and averaging more than 10 aces per set in the United Cup. He is undoubtedly a player whose ranking (still not even top-50) by no means reflects the quality of his tennis: starting the journey against Hubert would be a true ordeal.

Having analyzed the biggest hurdle, the list of candidates to complicate matters does not end there by any means. Two names that have also been hampered by injuries are those of Grigor Dimitrov and Matteo Berrettini: the Bulgarian came close to making Jannik's life difficult at Wimbledon, and even though it still seems too early for him to compete in five sets after his pectoral injury, he surely won't want to face him; if Matteo is serving well, Carlos already knows what he is capable of in Melbourne (he eliminated him in 2022). Other names that pose a significant threat are Tomas Machac or Alex Michelsen; the consistency of Jaume Munar or a rejuvenated Seba Báez could also turn the early rounds into a nightmare, while the surprise potential of names like Reilly Opelka or Giovanni Mpetshi Perricard also doesn't seem too appealing.

In the third round, new blood faces a variety of tough opponents

The top seeds would arrive in the third match of the tournament... and the array of players looming on the horizon is by no means a trivial matter. A finalist in Melbourne like Stefanos Tsitsipas, with renewed energy in this 2026, would create a high-profile clash (although Alcaraz and Sinner have his measure well); Joao Fonseca's back issues jeopardize his presence, weakening him as a potential tough nut to crack in that round, while others like Corentin Moutet seem far from having the necessary endurance to face a best-of-five sets challenge.

Therefore, the players most likely to pose challenges for Carlos and Jannik could be Learner Tien, who ended the year on a streak and delivered a remarkable performance last year, defeating Medvedev in one of the matches of the season; Valentin Vacherot, an X factor whose limited time on the circuit could be his strong suit; Cameron Norrie, a frequent nemesis of Carlos Alcaraz capable of capitalizing heavily on a bad day at the office, and Brandon Nakashima, displaying the best form among all candidates (was a finalist in Brisbane). We are only missing a Frances Tiafoe who usually competes well against the best in Grand Slams... but had such a dismal 2025 that he remains a complete mystery.

Strange as it may seem, the round of 16 would offer a small valley

That's how the ATP ranking looks right now, extremely volatile and not always rewarding recent form states. The potential opponents who appear in the round of 16 arrive with doubts, as is the case with Karen Khachanov (strange defeat against Mmoh in Hong Kong), Alejandro Davidovich (changed his coach before the start of 2026), or Jakub Mensik (still too inconsistent in five-set matches).

The name that offers the most security and perhaps the toughest opponent is Andrey Rublev, who knows perfectly well what it's like to battle against the best... but still mentally weak to overcome Carlos or Jannik in Slams. Further back from this group, there are appealing names that could surprise higher-ranked players to reach the round of 16: standouts being Flavio Cobolli or a streak from Fran Cerúndolo, but not much beyond that.

A big name to avoid in the quarterfinals: Daniil Medvedev

The quarterfinals present an even more complex situation. Two names placed outside the top-8 are in better form and seem to offer a more challenging time than the seeded players ranked from 5 to 8. The name to avoid and for many the third candidate for the title is Daniil Medvedev: if the Russian leaves behind his recent dismal streak in Slams and continues his form from the last three months, he will be a true nightmare and one of the few players with experience in beating the trendy pair.

The other contender to disrupt the draw is Alexander Bublik, recently breaking into the top-10... but his performance in Grand Slams is still a mystery, with a poor record (barely any quarterfinals at Roland Garros) and the perpetual question of whether his physical and mental strength can endure the demands of two weeks under the oceanic heat. Furthermore, Auger-Aliassime and Shelton will arrive with little competition rhythm (although Ben has an idyllic stage in Australia), while De Minaur and Musetti still appear far from matching the strength from the baseline of the Spanish and Italian.

In the semifinals, Djokovic or Zverev?

It's difficult to bet on one of these names as the toughest opponent in hypothetical semifinals. It seems clear that the experience and reputation of someone like Novak Djokovic tip the scales in his favor. Jannik and Carlos would prefer to see Sascha on the other side of the net, especially the Italian who clearly dominated him in last year's final; for Carlos, it would be a great opportunity to avenge the painful defeat of 2024. While the differences are not significant, it probably weighs more on the possibility of Novak making a comeback, arriving fresh and possibly relying on a highly offensive style of play in that round.
