Novak Djokovic has not dropped a single set in Wimbledon 2016. The Serbian will be keen to have the record intact as he prepares to square off against Sam Querrey in the third round of the competition on Friday.

The world number one is in unstoppable form in Grand Slams as he collected his 30th straight win, when he got past Adrian Mannarino in the last match. Djokovic might have found it easy against the unseeded player in the first two sets against the Frenchman, but the Serbian looked a bit shaken after Mannarino played good tennis in the third set.

Djokovic considered the victory to have come at the right time, with tougher matches ahead.

"The shots that he comes up with are very flat, and they bounce very low. He picks up the ball very early. Has a very good variety on his serve, slice that fades away from you. You know, he's definitely not easy to play against on grass. As I said, it was a very good challenge for me at the right time. I think I came up with the best game when it was most needed in all three sets," Wimbledon's official website quoted Djokovic  as saying. 

Djokovic's wobbly performance in the third set against Mannarino could give Querrey a bit of motivation to create an upset, which still looks a huge task. The American played a marathon of a five-set match in the first round to send Lukas Rosol home, and got the better of Thomaz Belluci in his last match in straight sets.

But Djokovic is in a league of his own, and cannot be compared to players, who Querrey has defeated so far. And the 41 ranked player is aware about it after having played as many as nine matches against the Serb to have lost eight times. Querrey's only victory came in 2012 Paris Masters round of 32, when he won from a set down. Such comeback talks a lot about the American's character, which needs to be show in abundance to stun the top seed.

Djokovic, in his first two matches, has showed his powerful game from the back, with some thunderous passes as well. Another similar performance from Djokovic can help him grab his pre-quarters spot.
