Rafael Nadal has said he views the rest of this year as "practically lost" for tennis and would even be relieved if the sport returned as normal at the start of 2021.
The men's and women's tours have been stopped due to the coronavirus pandemic, with Wimbledon cancelled for the first time since World War II and the French Open postponed until the end of September.
But Nadal, who has won 12 of his 19 grand slam titles at Roland Garros, believes the chances of tennis restarting before the end of this year are slim.
"I hope to play as soon as possible but if I think about it logically, we travel every week from one place to another, we are in contact with hotels, airports, all in different places," Nadal said in an interview with Spanish newspaper ABC on Tuesday.
"If you gave me the ability to guarantee that in January 2021, a normal season like before will begin, I would sign for that now with my eyes closed."
In a separate interview with El Pais, Nadal said: "I'm more looking to the Australian Open than what happens later this year. I see 2020 as practically lost."
