Jannik Sinner is motivated by the challenge of taking on Carlos Alcaraz as he looks towards 2026.

Sinner capped off the season by beating Alcaraz 7-6 (7-4) 7-5 to win the ATP Finals title on Sunday.

The 24-year-old became the youngest player since Roger Federer in 2003 and 2004 to win the ATP Finals in consecutive years.

This was the sixth meeting in a final between the world's best two male players in 2025, with the overall record between the pair now standing at 10-6 in Alcaraz's favour.

Sinner prevailed at Wimbledon, though that was wedged between defeats at Roland-Garros and Flushing Meadows, while the Italian had to retire due to illness in Cincinnati.

But Sinner, who will head into 2026 as world number two, is relishing the battle.

"[You've had] an amazing season, Carlos. Amazing what you’re doing. I know it’s a lot of work. Well deserved for the [year-end] number one," Sinner said during the on-court presentation.

Congratulations for the trophy and for the season @janniksin and team!  I hope to come back next year and fight for this title!  Grazie a tutti!

"You are definitely a player I look up to. A lot of motivation. I need this. The fans are very happy to see you play. You’re the most energetic player on Tour. Keep going. I wish you the best of luck. 

"I hope to see you again next year. Hopefully, there are great battles ahead of us.

"Facing Carlos, you have to bring your highest level. I served well when I needed to. He’s one of the best returners in the world — maybe the best — and that always pushes you to be sharp."

Alcaraz broke Sinner at the start of the second set, but was unable to halt the second seed's momentum once he conceded a game of his own midway through the set.

But the Spaniard was not displeased with his performance.

"I'm just really, really happy with the level I played today," said Alcaraz.

"I just played against someone who hasn’t lost a match on an indoor court in two years."
