Since Carlos Alcaraz’s split with Juan Carlos Ferrero, there have been predictions that the Spaniard might have his worst season in 2026. That prediction has fueled the belief that his arch-rival Jannik Sinner may win all four major tournaments. But former ATP player Greg Rusedski doesn’t believe Sinner can win all the four Grand Slams this year.
Alcaraz’s sudden split with Ferrero leaves room for unpredictability. The Spaniard has never been without the former French Open champion for the past seven years on tour. Their partnership was fruitful, as Alcaraz won six Grand Slams in four years, more than any player on the ATP Tour during that period.
But he will have to chart a new course without Ferrero for the first time in his career and will be under immense pressure to do so. But that’s not the case for Sinner, who did well to keep Darren Cahill by his side despite the Australian coach announcing that he would leave Sinner’s team at the end of the 2025 season.
Sinner looks more composed going into the 2026 season and he’s the red-hot favorite to win the Australian Open for the third consecutive time. His expectations of doing so increased since Alcaraz announced he had parted ways with Ferrero. Sinner is currently the best hard-court player and will be aiming to win his 5th Grand Slam.
Besides that, Sinner also has a chance of winning the French Open, Wimbledon, and the US Open in 2026. During a conversation on the Off Court with Greg podcast, Greg Rusedski analyzed that he doesn’t see Sinner winning the four Grand Slams in 2026. The former British player pointed out that legends such as Roger Federer, Rafael Nadal, and Novak Djokovic have failed to do so:
I don’t think he will win all four, no. But if he wins in Australia, where he is the big favourite, and then gets the French Open, then we will all be talking about it. We saw Novak try to do that a few years back and he was one match away against Daniil Medvedev at the US Open and lost it at the final hurdle after winning three majors. If anyone can do it, it’s Jannik. He has great memories of Australia at the start of the year, but can he bounce back and win the French Open?
Should Alcaraz surprisingly win the Australian Open, he will become the youngest men’s player to complete a Career Grand Slam. He has won all three remaining Slams in his career. Likewise, Sinner, if he wins the French Open in June, will complete a career Grand Slam, but not as the youngest player to do so.
Greg Rusedski discusses Carlos Alcaraz and Jannik Sinner’s chances of success in 2026
Carlos Alcaraz was heavily criticized during the pre-season for taking part in exhibition tournaments, while his arch-rival Jannik Sinner was in Dubai enjoying his holiday and working on his game with his team. The Spaniard will play his third exhibition match against Sinner in Seoul, South Korea, just eight days before the Australian Open.
During the aforementioned conversation, Greg Rusedski pointed out that Alcaraz has question marks heading into the 2026 season because of his coaching situation and his participation in exhibition matches. He added that Sinner looks to be improving and working on his game ahead of the Australian Open:
Also with Carlos Alcaraz, where is he going to be. There’s lots of question marks going into the season, but Sinner keeps improving. I’ve been watching videos of him preparing in Dubai and he is getting stuck in. He’s working in approaching the net and improving. He is a complete player and this thing upstairs, the brain, it’s unbelievable how strong he is.
Alcaraz and Sinner will not take part in any warm-up tournament like most players are doing. It isn’t the first time the duo has decided not to participate in any tournament ahead of the Australian Open.
