LISBON: Rafa Nadal has raised doubts about his participation in this year’s Tokyo Olympics amid the COVID-19 pandemic, saying on Tuesday that he has to be flexible and cannot give a clear answer until he organises his schedule for the year. Japan has extended a state of emergency in Tokyo and three other areas until the end of May as the country battles a surge in COVID-19 cases, raising new questions about whether the rescheduled July 23-Aug. 8 Games should go ahead. Nadal, who won a singles gold in Beijing 2008 and added a doubles title in Rio de Janeiro eight years later partnering Marc Lopez, said that he is yet to firm up his plans on travelling to Tokyo. “I don’t know yet. Honestly I can’t give you a clear answer because I don’t know. I don’t know my calendar,” Nadal told a news conference at the Rome Masters. “In a normal world I’ll never think about missing Olympics. There’s no doubt about that. Everybody knows how important it has been for me to always play in the Olympics. Under these circumstances, I don’t know”.
