Top-seeded tennis players Rafael Nadal of Spain and Novak Djokovic of Serbia will vie for the trophy today at the sold-out 2016 Qatar ExxonMobil Tennis Open finals.

World No. 1 Djokovic, who racked up 11 titles including at the US Open, Australian Open and Wimbledon during the 2015 season, has never clinched the Qatar tournament.

Nadal is the 2014 champion, but shocked fans last year after failing to advance past the first round of the 2015 open.
