A superb Jannik Sinner has contested four consecutive Grand Slam finals, winning three of them in the last 10 months.
World No. 1 Sinner, who held three championship points against Carlos Alcaraz in last month's Roland Garros final, came within one point of attaining the Sinner Slam—holding all four major championships simultaneously.
So what does the Wimbledon winner do for an encore?
Retain Darren Cahill on his coaching team.
A new report in Italian publication Corriere Della Sera written by Gaia Piccardi says Coach Cahill will continue as working with Sinner in 2026 as co-coach to Italian Simone Vagnozzi.
"The collaboration between the two began at Wimbledon three years ago and will continue in 2026," Corriere Della Sera reports.
Cahill, who has guided Lleyton Hewitt, Andre Agassi, Simona Halep and Sinner to the world No. 1 ranking and now has completed a coaching Grand Slam, reportedly applied his coaching status to inspire Sinner before Wimbledon.
Cahill told Sinner "If you win Wimbledon, you will be the one to decide if I stop coaching at the end of the year."
Incentivized by that vow, Sinner snapped Alcaraz's 20-match Wimbledon winning streak and his own five-match losing streak to the second-ranked Spaniard.
So now, Cahill, true to his word, will return in 2026 though he won't travel as much, while Vagnozzi is expected to be by Sinner's side throughout the 2026 season.
Asked directly about his role going forward after Sinner dethroned two-time Wimbledon champion Carlos Alcaraz 4-6, 6-4, 6-4, 6-4, Cahill was coy in a Sunday evening press conference at SW19.
"I don't want to answer this," Cahill said with a smile. "You now what, you just need to ask Jannik that. Ask Jannik."
The 23-year-old Italian said he's proudest of the resilience he displayed—and the mental work he put in with coaches Cahill and Vagnozzi—to bounce back from a gut-wrenching French Open final defeat.
"This I think is the part where I'm the proudest of because it really has not been easy. I always tried to be honest with me and had the self-talk too, you know, what if, what if?" Sinner said. "I always tried to accept it, in a way.
"Things can happen. I believe if you lose a Grand Slam final that way, it's much better like this than someone kills you, you know, that you make two games. Then after you keep going, keep pushing.
"I did a lot of intensity in every practice because I felt like that I could play very good. That's why I also said after Roland Garros that it's not the time to put me down, no, because another Grand Slam is coming up, and I did great here."
