Niki Lauda has confirmed reports that he is recovering well from his mid-year lung transplant.
The Mercedes team chairman missed the end of the 2018 season as he recovered in hospital and a rehabilitation clinic, but Lauda told Kurier and Osterreich newspapers that he is now at home.
"At the end of January, I'm throwing away the walker," said the 69-year-old.
"The lungs work perfectly, but I've been in bed for five months so the main problem is the muscles. All I have to do now is gain more strength.
"I feel good and I am not taking as many pills as before. Everyday life is not the same as before, but every day I make progress with my two physios.
"I use the tennis court in front of my house as I need the flat surface to learn how to walk properly again.
"According to the doctors, I will recover completely," the F1 legend added.
