Carlos Alcaraz has missed training and began wearing a nasal strip as he battles a cold before the Rotterdam Open.

Carlos Alcaraz said on Sunday that the form of Australian Open champion Jannik Sinner is “crazy”, as the Spaniard prepared for his first match since losing in the quarterfinals in Melbourne.

Carlos Alcaraz has given an update on his physical health after suffering from an illness in the build up to his debut at the Rotterdam Open. The 21-year-old will play world No 84 Botic van de Zandschulp in his first match at the ATP 500 tournament on Tuesday.
