Aryna Sabalenka puts French Open rivals on alert with six-word message

has told her rivals, "I'm motivated more than I was last year" in a terrifying message from the world No. 1. She is gunning for her first title at Roland Garros after wins in Melbourne and New York last year.

But one Paris restaurant has lost a customer after a dodgy meal put paid to Sabalenka's hopes last year. World number one Sabalenka was doubled over with stomach trouble as she fell to defeat to teenager in the last eight.

The Belarusian has vowed to watch what she eats at the home of haute cuisine this year as she bids to add a maiden Roland Garros to her US and Australian Open titles.

"I'm definitely not going to go for the same meal I had before that quarter-final match. The lesson is learned," she said. "Since then we did a couple of adjustments on my food, and yeah, just make sure that it's never going to happen again.

"Of course I'm super-motivated, because I felt like last year I was really ready to be in the last stages of the tournament, but yeah, my body didn't really feel the same. I'm motivated more than I was last year."

Sabalenka kicks off her tournament against Russian Kamilla Rakhimova on Sunday.

Former world number one and four-time champion Iga Swiatek has not won a title, or even reached a final, since last year's Roland Garros victory.

The 23-year-old from Poland has slipped to number five in the world, but hopes returning to Paris will reignite her game.

"I love playing tennis here," she said. "I feel like, just good here, you know. And off the court, it really feels like home. I have my places and my routines. I just like coming back here.

"On the practice court I have been playing great. My tennis is good, so I just need to do that in the match."

Swiatek begins her bid for a fourth straight title against Slovakian Rebecca Sramkova, and could meet Britain's Emma Raducanu in round two.

France's Caroline Garcia will bid farewell to her home grand slam this year after the former world number four announced her impending retirement.
