Novak Djokovic attempts to continue his winning run at the Miami Open in Key Biscayne, Florida when he meets Portuguese Joao Sousa in Round of 32 of the tournament.

Djokovic, who is looking to tie Andre Agassi with six Miami Open titles, improved his record this year to 23-1 after defeating Great Britain’s Kyle Edmund 6-3 6-3. After the match, the Serb was praised Edmund’s display, saying that the 21-year-old Englishman has the potential to become one of the top players in the sport.

"He definitely does have the potential to step up and get up to the top of the game," Djokovic said, reports Super Sport. "Very pleasantly surprised with his game, his passion on the court."

The 11-time Grand Slam winner next faces Sousa, who defeated Canada’s Vasek Pospisil in three sets 6-7(1) 7-6(5) 6-2. Djokovic leads Sousa by 2-0 in their FedEx ATP Head2Head matchup, having defeated the world No. 38 at the US Open and Roland Garros in 2013 and 2014, respectively.

Djokovic is the huge favourite to win the Round of 32 clash against Sousa, considering the Belgrade native’s dominating performance in recent tournaments. However, the 26-year-old Portuguese would still prove as a challenge for Djokovic after Sousa’s impressive win against Pospisil.

The winner of between Djokovic and Sousa could either face Japan’s Yoshihito Nishioka and Austrian Dominic Thiem in Round of 16.

Meanwhile, with Rafael Nadal and Roger Federer withdrawing from competition at the Miami Open, there is less competition for Djokovic to a third-straight title.

Nadal withdrew from the tournament after retiring hurt in the third set of his match against Bosnian Damir Dzumhur due to a dizzy spell, while Federer had to postpone his first competition from a knee surgery because of a stomach virus.
