McLaren were the first team to withdraw from the Australian Grand Prix. A team member had tested positive for the coronavirus. Since then, another fourteen team members have been self-insulated on site. As a precaution, Carlos Sainz is doing the same thing now that he's back in Europe.
The Spaniard shows no signs of the virus but is on the safe side in case he has been in contact with one of the infected team members.
In his message, Sainz also wants to support the team members who are still in Australia. They all give him a big hug and he believes in a happy ending, so that everyone can quickly think about racing again.
