Andy Roddick predicts who will have the better tennis career out of Jannik Sinner and Carlos Alcaraz

Carlos Alcaraz and Jannik Sinner have continued their impressive careers at this year’s French Open, where both players are into the quarter-finals.

Sinner has been backed to win the French Open, which Alcaraz won in 2024 after his final success over Alexander Zverev.

Zverev also lost this year’s Australian Open final to Sinner, who currently occupies the top spot in the ATP rankings.
