Niki Lauda has said that he is not sorry about criticising Max Verstappen's aggressive driving.

Amid widespread criticism of the 18-year-old's driving at Spa recently, F1 legend Lauda suggested that Verstappen needed a "psychiatrist".

The Red Bull driver and teenager hit back: "If I go, then we might as well go together."

Now, Mercedes team chairman Lauda has responded yet again, telling Sky Italia: "Go together? Sure, but then the psychiatrist will decide which of us needs to stay."

"I think Max has an incredible talent, but there is a limit to what you can and cannot do on the track and someone needs to point it out to him. The problem is that Max is very young. But if we do a balance between talent and youth, then his talent wins."

Verstappen will start fourth on the grid in tomorrow's Singapore Grand Prix.
