4 Nico Rosberg

Four seasons into his career, no-one is quite sure whether 1982 Formula 1 world champion Keke has passed his grand prix-winning genes onto his son Nico.

During four rollercoaster years with Williams, Rosberg has proved that he can be quick, but the overall performance of the team and, in recent years, weak team-mates has made it difficult to draw conclusions.

This year, he is up against Michael Schumacher at Mercedes and the intelligent, articulate Rosberg has the chance to prove just how good he is.
