Janik Sinner's anticipated rise to world No.1 was officialised on Monday when the ATP released its new rankings, making him the first Italian ever to hold the top spot.

Jannik Sinner said his burgeoning rivalry with Carlos Alcaraz is "exciting" for tennis after losing in five sets to the Spaniard in the French Open semi-finals on Friday.

Carlos Alcaraz beat incoming world number one Jannik Sinner 2-6, 6-3, 3-6, 6-4, 6-3 on Friday to reach the French Open final and continue his bid for a third Grand Slam title.
