Novak Djokovic equalled Rafael Nadal's record for the most ATP Masters 1000 titles as he beat Stefanos Tsitsipas in the Madrid Open final.
Djokovic clinched his 33rd Masters title - and third in Madrid - with a 6-3 6-4 victory.
Tsitsipas, the exciting 20-year-old from Greece, had stunned Nadal in the semi-final but had no answer to the world number one on Sunday.
Djokovic, who did not face a break point throughout the match, broke in the second game of the contest and breezed through the rest of the set.
The Serbian broke in the ninth game of the second set before securing victory on his third match point.
