Rosberg has spent his whole F1 career with the team, and has said that this weekend will be strange because of it.
It’s widely expected that he will be off to Brawn – a straight swap with Rubens Barrichello is rumoured – or to McLaren as replacement for Heikki Kovalainen.
Mercedes – whose engines power both teams’ cars – want a German driver as they’re a German company, and Rosberg is the strongest prospect (even though his famous father Keke is Finnish, Nico is actually German).
So which team do you think he’s most likely to be in? And how will he fare against either teammate – Jenson Button or Lewis Hamilton?
