Formula 1 chief warns Ferrari against leaving the sport

"I do not want to see them leave. It will be painful for them not to be involved in the sport."

FIA president Jean Todt believes Ferrari will suffer if they follow through with their threat to leave Formula One.

Ferrari CEO Sergio Marchionne raised the possibility of the famous Italian constructor quitting the sport if Liberty Media, F1's new American owners, go ahead with their proposed engine changes.
