Tennis legend John McEnroe channeled his inner Charles Barkley with his no-holds-barred opinion on Carlos Alcaraz’s new hair.

When Alcaraz arrived at the US Open practice courts on Tuesday, his full head of hair was missing, replaced with a buzz cut.

Carlos Alcaraz 's haircut rather than his tennis was the talk of the US Open as the second seed eased into round two in New York. The Spaniard arrived at Flushing Meadows on Monday ahead of his clash with Reilly Opelka looking almost unrecognisable after shaving his head.
