But speaking to Spain's sports media on Monday as part of the launch of a new campaign to raise money to fight the virus, Nadal said: "I think one thing is the training and another thing is the competing.
"With tennis I don't see a problem with training with another professional although it's not the priority for anyone at the moment.
"But competing is a lot more difficult. I wish we could compete even without spectators.
"But we have to be responsible and coherent. I don't see how we can travel to a different country every week.
"Our sport is very different to golf where there is a lot more space.
"And to hold a Grand Slam tournament there are 128 men and 128 women players, as well as all the members of each player's team."
"Even without spectators there would be a lot of [physical] contact."
Repeating his feeling that training should be allowed he said: "When it comes to training I think they should differentiate between sports."
Nadal has teamed up with Spanish basketball legend Pau Gasol and other leading figures in Spanish sport to raise funds for the Red Cross.
