Carlos Alcaraz believes the sky is the limit after becoming the first player to beat Rafael Nadal and Novak Djokovic at the same tournament on clay as he stormed into the Madrid Open final on Saturday. 

The Spaniard, 19, reached his second ATP Masters final in five weeks and claimed his first win over a reigning world number one, overcoming Djokovic 6-7 (5/7), 7-5, 7-6 (7/5) in front of a sell-out home crowd at the Caja Magica.
