'They are our heroes': Tennis champions' beautiful act amid crisis

Rafael Nadal, Roger Federer and Novak Djokovic have all offered words of encouragement from self-isolation as they urge everyone to pull through the coronavirus pandemic.

With competitions suspended around the world, the ‘Big Three’ like most of the tennis world have gone into self-isolation during the pandemic.

Nadal took the time to send a heartwarming message to praise the “heroes” in the health industry and government fighting everyday to help others.

Spain has been one of the hardest hit with the coronavirus and the 19-time Grand Slam champ thanked those in the ‘first line of fire’.

"I wanted to send a message of thanks to all the doctors, nurses and all the health personnel who are all protecting us, and to the police forces, civil and national guard, the army, and all those who make us feel a little safer, who are in the first line of fire," he said, in Spanish, on Instagram.

"They are our heroes. I want to express my admiration and thank you all."

"There are also positive things in these difficult times. We are demonstrating to be a united people," Nadal said.

Federer urges everyone to keep safe

Federer also took the time, following his knee surgery, to send some encouragement during these dark times.

The Swiss maestro’s latest public service announcement about the threat of COVID-19 is one of the most important he's made in a glittering tennis career.

“I wash my hands very frequently as we’re supposed to. I believe helping each other is more important now than ever, especially because we want to help the older generation.

“They’re the ones at highest risk, and we need to help them by keeping a distance of two metres and not shake hands.

“It’s really important to take these rules seriously. Very very seriously.

“Eventually, we could all be in quarantine and not be able to leave the house anymore, so I really hope all of us take it very seriously.”

Djokovic shares message of support

World No.1 Novak Djokovic posted a photo of himself with his family during play-time with his children during isolation.

He also wished everyone the best during these unprecedented times.

Both the ATP and WTA announced this week there will be no tournaments played until June at the earliest, meaning Federer will miss very little to no tennis while he recovers from knee surgery.
