"Already thinking how to convince the doctors to be on the grid for tomorrow!"
Sainz did not take part in Saturday's qualifying for the Russian Grand Prix.
Earlier team boss Franz Tost refused to rule out the Spaniard racing come Sunday's event.
"If he is able to continue the race or not we don’t yet. When he comes back we will check and then we will see.
"First of all we want to have Carlos back here with us then we will ask him and discuss whether it makes sense to do qualifying or not.
"We do not want to go for a risk for this because he had a heavy accident."
