Would you explain or rephrase the underlined part?

"I really enjoy all the tracks coming up but anything can happen in racing, I could make a mistake, so it's a matter of seeing what happens," he said, as he prepares for the next stop at Assen in the Netherlands. "Each race is a clean slate for me and because I won the previous race has nothing to do with it. We don't just expect that form to continue, we know we have to continue to work hard."
Exactly the focus that our former Champion needs to stay on course.
Congratulations to Casey for continuing his roll toward MotoGP Glory!

Thank you,

This is an interesting question. The writer has simply omitted "This is" (or something similar) from the start of the underlined sentence.

As written, that sentence is not complete, and you're right to wonder about it. But this is a conversational style. If we were talking, and you said something, and I wanted to agree with you, I could just say, "Right." I don't need to say "You're right", although strictly speaking, "Right" isn't a complete sentence. It's the same idea here. He is building on the previous paragraph, and adding his comment in a way that isn't grammatically complete but still conveys his meaning, just like saying "Right" would do.
Thank you, that made sense.Emotion: smile
