Former Australian tennis player Sam Groth believes world No. 4 Alexander Zverev poses the biggest threat to Novak Djokovic at the US Open. Djokovic, ranked at No. 1 in the world, enters the US Open as the top favorite to win it all and capture a Calendar Grand Slam.
Djokovic hasn't lost a match at the Grand Slam level this year, proving that he is still as dominant as ever on the biggest scene. However, Djokovic failed to win gold medal at the Tokyo Olympics after suffering a surprise loss to Zverev in the semifinal.
“You come into this event and you think who can beat Novak in five sets? I think personally Zverev is probably the best chance. He’s the biggest threat," Groth said during his appearance on The First Serve.

Groth hopes her fellow compatriot Barty -- who won Wimbledon -- will win the US Open and claim back-to-back Grand Slam titles. “As I look through what she’s got to get through, when I look through the draw especially on her side, I don’t see a lot of names I see as huge threats.
It would take her having an off day," Groth insisted. Djokovic and Barty both enter the US Open as the top favorites to make it all the way. "I have had lots of time to rest, really much time for a tennis player.
It has been three and a half weeks since my last match. We have gotten used to it. Tennis is being played throughout the entire year, we haven't had lots of time to rest, especially in an Olympic year. I have had a great summer, it exhausted me a lot, but I can't be complaining.
I have had my best season when it comes to Grand Slams and I hope to conclude the year with one more victory," Djokovic said.
