(Click CC for subtitles) Rumors fly about whether an up-and-coming driver will join Hamilton on team Mercedes, potentially leaving Valtteri Bottas without a seat. Seemingly permanently stuck in the crisis of a one-year contract running out, this time Bottas has Mercedes golden boy George Russell breathing down his neck. The young Brit desperately wants Bottas’ seat, and things come to a head when the two collide at Imola. Scandalous.
Bottas can’t resist the inevitable though, and after Russell puts the F1 on the front row at Spa, whilst the Finn can only manage eighth, it looks to be all over. Thus follows a scene of Russell being told he has the Mercedes seat by Wolff in a scene which looks so staged it would make even cringe.
