The Manchester City boss supported his compatriot as Alcaraz beat Sinner in four sets to claim the final grand slam title of the year and world number one ranking. The 22-year-old Spaniard won 6-2, 3-6, 6-1, 6-4 to beat his close rival in a superb performance that will no doubt have impressed Guardiola. The City boss was not the only big name to visit Flushing Meadows for the tennis showpiece on Sunday, with U.S. President Donald Trump, basketball star Steph Curry, and Friends actor Courteney Cox also in attendance.
