Novak Djokovic overcame a stern test from Marton Fucsovics to reach the last eight of the Qatar Tennis Open. 

Fucsovics, coming off the back of a career-best season in 2018, deservedly claimed the opening set in Doha and initially proved equal to an improved effort in the second from the world number one.

However, Djokovic eventually claimed a break of serve to level the match and was clinical thereafter as he completed a 4-6, 6-4, 6-1 victory in two hours.

Djokovic – the winner of this event in 2016 and 2017 – has now won 12 matches in a row in Qatar and will face Andrey Rublev or Nikoloz Basilashvili in the quarter-finals.
