Djokovic eyes No.1 as US Open gets underway

Novak Djokovic launches his quest for a 24th Grand Slam singles title on Monday as the US Open gets underway with the Serb needing only a first round victory to reclaim the world number one ranking.

The 36-year-old Serbian star makes a long-awaited return to the USTA Billie Jean King National Tennis Center after missing the 2022 tournament due to his refusal to get vaccinated.

Second seed Djokovic headlines the night session on the 23,000-seater Arthur Ashe Stadium with what should be a straightforward opener against France's world number 84 Alexandre Muller.

A victory will guarantee Djokovic returns to the top of tennis's global rankings, regardless of how the rest of the US Open fortnight pans out.

Djokovic needs just 20 points to regain the No.1 ranking after defeating current No.1 and defending US Open champion Carlos Alcaraz in the Cincinnati Open earlier this month.

Alcaraz, who defeated Djokovic in a five-set Wimbledon final classic in July, opens his US Open campaign on Tuesday.

While most neutrals are hoping that Alcaraz and Djokovic can progress through to another blockbuster showdown in the men's final on September 10, Djokovic says he is looking no further than Monday's opener.

"You can't really be thinking about what happens in three or four days," Djokovic said on the eve of the tournament.

"It's also in a way disrespectful to your next opponent if you're already thinking about your finals matchup...that kind of mindset never really resonated with me."

History suggests however that Djokovic's opener on Monday should be a formality: the Serb has not lost in the first round of a Grand Slam since the 2006 Australian Open.
