Novak Djokovic’s coach Marian Vajda has made a worrying statement about the former world number one after the Serbian’s French Open exit, the Daily Express report.

Djokovic, who seemed to be back to his best during the early rounds of the competition, suffered a surprise exit at the quarter final stage to unseeded Italian Marco Cecchinato.

The 31-year-old went out at Roland Garros in four sets which included two tiebreak defeats, something Djokovic has normally exceled in throughout his glittering career.

Djokovic also admitted straight after his defeat that he is unsure if he will compete at Wimbledon next month, which came as a surprise to many.

Talking after Djokovic’s exit, coach Vajda, who returned to help Djokovic on a temporary basis earlier this year, said:

It definitely wasn’t Novak. He wasn’t controlling the points, and yet it seemed better on 5-2 in the third set. He became nervous. I don’t know what he was thinking about. Novak is not at 100 percent. He needs matches.

It is still unknown if Djokovic will be competing on grass this year, with a decision to be made by the end of the month.
