World number one Novak Djokovic remains without an ATP Tour title this season after losing to Russia’s Andrey Rublev in the final of the Serbia Open.
Djokovic fought back from a set down for the fourth time this week in front of his home fans in Belgrade, but ran out of steam in the decider as Rublev powered to a 6-2 6-7 (4) 6-0 victory in two hours and 29 minutes.
