Kubica: I have a lot more to lose than people think

Kubica, who will partner rookie George Russell at Williams next year, told Sky F1, "I wouldn't be coming back if l didn't think l could do it properly. I have a lot more to lose than people think. The big part of the job we have to do is off track. To develop the car and bring Williams back to where it should be."

The 33-year-old Pole's well-told story must rate as one of the greatest comebacks in our sport, gutsy and brave ranking up there with the 1976 tale of Niki Lauda's return to the cockpit only weeks after his near-death accident immortalised in the movie Rush.

Surely one day, in the future, Kubica's story will also be made into a movie with a possible intro scene inadvertently but aptly described by himself to Sky F1, "Twelve months ago l realised l can do it and realised l could drive as naturally as l did before."

"The most important day of my life was 12 months ago when l knew l could do it. I honestly think l am now more ready than l was before."

"My doubts were gone last year in my second or third test in an F1 car. The question marks were related in a technical point of view: how the new car will suit you, how the new tyres will suit you. But this is the same for every driver in the paddock."

"It is the end of a long journey and it has been a big challenge to get here. But now it's the start of a new challenge," added Kubica who will line-up on the F1 for his 77th grand prix in Melbourne on 17 March.
