"I have to stick to F1. That's the priority at the moment and for the future. That's what I have to do, it's what I'm trained to do," he said.
"I really want to concentrate and get a good chance to do it properly. I really feel it's unfinished business for me in F1. I feel it's where I belong.

"This has been a downward slope but I'm sure we'll bounce back.
"You begin to realise just how much you love it when it's taken away from you."
