#4 Novak Djokovic
The former world number one has been in good form so far at the Championships, dismissing his opponent in round two for the loss of only five games, which came after his first round opponent retired in the second set due to an injury. The third round saw him make short work of Ernests Gulbis in straight sets.
Since winning the Roland Garros in 2016, Djokovic has not been able to add any other Grand Slam title to his kitty. He has found the going tough in Grand Slams recently and is nowhere near his imperious best.
After splitting with Boris Becker, the Serb is now working with the legendary Andre Agassi. Having won the Eastbourne International before Wimbledon, he would look to kick into higher gears moving into the final days of the Championship.
