(((((((US))))))) US Open Tennis 2018 Live Stream Watch Free Online Game

Djokovic, 31, triumphed in New York in 2011 and 2015 and has reached five other finals at Flushing Meadows.

Since 2007, he has reached at least the semi-finals every time he has competed at the U.S. Open.

He will confirm his place in this year's quarter-finals by beating Sousa, and there is little reason to suggest he won't continue his perfect record against the 29-year-old.

The second week of the 2018 U.S. Open gets under way on Monday at Flushing Meadows in New York, and two-time champion Novak Djokovic is in action at Arthur Ashe Stadium in the afternoon session.

The No. 6 seed faces a fourth-round clash with Portugal's Joao Sousa, who he has beaten in all four of their previous meetings without dropping a set.

America's Madison Keys kicks off the action at Arthur Ashe against Dominika Cibulkova in what should be a tight contest, while Kei Nishikori, Marin Cilic and David Goffin are all set to turn out at Louis Armstrong Stadium.

Here is the schedule for Monday afternoon, per the tournament's official website:

Arthur Ashe Stadium (Play begins noon ET, 5 p.m. BST)

(14) Madison Keys vs. (29) Dominika Cibulkova
