World No.3 Novak Djokovic believes not having a run on grass ahead of Wimbledon is going to hamper his chances of winning his fourth straight title at the All England Lawn Tennis Club when action commences on June 27.

In each of his past two Wimbledon title runs, the Serbian’s opening match on SW19 was his first grass-court match of the season. Even this year, the winner of 20 majors has not played a tournament on grass coming into Wimbledon but it doesn’t seem to affect Djokovic.
