Roger Federer has admitted that he is doubtful on whether he will be taking part in the 2017 French Open in May.
Following his win in Miami, the 35-year-old, who had now won 19 of 20 matches in 2017, revealed his intentions to take a 10-week break, skipping the entirety of the clay court season before the French Open begins on 22 May.
However, the former world number now seems unsure on whether he will still feature in Roland Garros.
"I will decide whether to switch to clay or not on May 10," he said, as quoted on TennisWorldUSA. "We will sit and speak about it: will we skip the clay season? Or it's better not to do it?"
"Until then I will practice on hard. I will compete only when I'm ready and motivated."
While Federer has not found as much success in the French Open, having only won it once in 2009, he believes playing in the Grand Slam would be good preparation for Wimbledon.
"I maybe play my aggressive tennis there too, because when the weather is good courts are very fast, maybe faster than Wimbledon," he added. "So it would be a good preparation for the grass season."
Federer previously mentioned that he did think momentarily about retiring on a high following his win in Melbourne, but when asked if he would do it if he were to win Wimbledon this year, he replied by revealing he is already planning his tennis for next year.
"I never thought about it," he explained. "I am already planning the beginning of 2018. I don't think wins or losses can influence the date of my retirement."
"It's more a mind and physical question. It's not my goal to stop playing when I am peaking. I will play until when I can and until when I will be happy to do it as well as my family and team."
