Massa should be on pretty light fuel, though. But generally, I agree. Norbert Haug has said, that Massa is not Lewis's rival in this race. I'm sure they've taken Lewis aside and hammered it into him to not do anything stupid and just finish (at least 5th, of course).
I'm really excited about tomorrows race. I hope it gets as interesting as it promises to be. If nothing else there will at least be the suspense of whether Lewis's engine holds up.
