Mercedes are looking for a big step up on last year and the signs so far are encouraging. Rosberg completed the most miles in testing of any driver and Schumacher, starting the third year of his comeback and still chasing his first win since 2006, has sounded upbeat.

The Brackley-based team have invested heavily in technical staff and principal Ross Brawn is confident the car is a significant improvement. If so, Rosberg could be closer than ever to his first win and Schumacher his 92nd.
