Valtteri Bottas has got what he wanted; a fourth season alongside Lewis Hamilton at Mercedes. It's a vote of confidence in him, albeit not as emphatic as a new multi-year deal would have been. So what does he need to do next season to ensure it is not just a case of one more season?
The man himself remains focused on becoming Formula 1 world champion, as you'd expect for someone who only turned 30 on Wednesday. He reiterated his determination to do that on Thursday, but Mercedes doesn't need Bottas to become world champion. His role is far more nuanced than that, and consequently almost as difficult to perform.
Bottas famously said "that hurts" when confronted with Toto Wolff's suggestion he had been a "sensational wingman" for much of last year's Hungarian Grand Prix. But that's exactly what Mercedes needs him to be. Yet the role of the unofficial number two driver is often misunderstood and there's far more to it than simply driving around and being slower than Hamilton more often than not.
