Paris - Serbia's second seed Novak Djokovic has opened his bid for a maiden French Open title on Monday with a 6-1, 6-2, 6-4 first round win over Portugal's Joao Sousa.
"I played for most of the match quite solid. The end of the match was not so nice from my side because I dropped my serve twice," said Djokovic.
"It was very heavy conditions. The court is not that great, or in a great condition at this moment.
"But of course, considering the amount of the rain that we had in last four or five days, it is not easy for people to maintain the court in the right state. They are doing their best," he added in reference to the Philippe Chatrier centre court.
Rafael Nadal who also advanced easily to the second round with a straight sets win over American Robby Ginepri was the first player to question the quality of the centre court.
Organisers shifted his match onto the Suzanne Lenglen arena despite the Spaniard being an eight-time winner in Paris.
"I think they made the court new, so it's like the clay gets a little bit more fixed. It was moving around a little bit too much and some small stones make the movement a little bit more difficult," said Nadal.
Djokovic continued to add to the controversy by saying the court had worsened over the first two days of the tournament.
"In my opinion there are a few times today they maybe should have covered the court earlier," continued Djokovic.
"I think the chair umpire should have made a decision earlier to take us off the court and cover the court. I'm talking for the court's sake, you know, for a good condition, because there was a lot of rain.
"I know that on clay, of course, we can play with a certain level of rain, but still it's not that great for the court's condition."
The Serb, who is coming off a stellar showing in Rome where he defeated Nadal, following earlier victories in 2014 at Indian Wells and Miami, converted eight of 15 break points.
He also rained down eight aces behind a first serve percentage of just under 70 per cent in a match that lasted 1hr 46 minutes.
The former world number one now faces French hope Jeremy Chardy for a place in the last 32.
"Playing a French tennis player in France, we all know how challenging that is," he said.
"He had a big win against (Roger) Federer in Rome, so I'm sure he's very motivated to play his best."
Six-time Grand Slam winner Djokovic is only missing the Roland Garros title to complete his set of all four majors and began in style with a confident showing.
During a match interrupted by rain, the 27-year-old Belgrade native was at his charismatic best on and off the court as he even had time to chat extensively with a ball boy during a brief rain delay.
He offered the young lad a drink and clinked bottles with him as the crowd roared their approval.
