Carlos Alcaraz continued his impressive rise by shaking off injury to beat Rafael Nadal and set up a Madrid Open semi-final against Novak Djokovic.
The 19-year-old Spaniard produced some superb hitting to beat five-time champion Nadal 6-2 1-6 6-3.
Alcaraz was struggling to move after falling and injuring his right ankle in the second set but managed to regroup to close out a stunning win.
World number one Djokovic earlier beat Hubert Hurkacz 6-3 6-4.
Alcaraz has often been compared to Nadal during his meteoric rise, which has seen him win the Miami Open and break into the top 10 of the world rankings.
