Former coach of eight-time Grand Slam champion Andre Agassi, Brad Gilbert, called world number two Jannik Sinner's game "outrageous". "If you put Agassi and Novak Djokovic in a blender, you get Sinner," he said, adding, "What is more impressive is that he is nowhere near the finished product." Sinner recently lost to Carlos Alcaraz in the US Open 2025 final.
