Djokovic optimistic despite lowered expectations at Roland Garros

Defending champion Novak Djokovic aims for record 25th Grand Slam title at French Open despite wobbly season.

Defending champion Novak Djokovic will have low expectations and high hopes at the French Open this year, but the top-ranked Serb said on Sunday that he knew how to raise his game on the biggest stage despite a wobbly season.

Djokovic has had a bumpy few months by his own admission after the 37-year-old was denied a record-extending 11th title at the Australian Open by eventual champion Jannik Sinner in January, with erratic form affecting his rhythm thereafter.

Having belatedly arrived at the year's second major hoping to claim a record 25th Grand Slam and move past Margaret Court, Djokovic said he was cautious but also confident ahead of his opener with local hope Pierre-Hugues Herbert.

"I know what I'm capable of, and particularly in the Grand Slams I normally play the best tennis, at least I aim always to play the best tennis and I was most of my career able to do that, so that's the goal," Djokovic told reporters.

"I've been saying for quite a while that in terms of clay I want to peak here in Paris, in Roland Garros. Last year I had an amazing year and particularly here.

"Hopefully I can have a great tournament."

Djokovic's build-up to the major has hardly gone according to plan, as he crashed out of Rome two days after being hit on the head by a fan's water bottle while signing autographs earlier this month.
