Nico Rosberg badly needed this result. More than he let on, probably. And in a Formula 1 race where Mercedes comprehensively asserted itself over a resurgent Ferrari, it was imperative that Rosberg took a big step towards arresting the incessant momentum that team-mate Lewis Hamilton built up in the title race across the first four grands prix of the season.
So far this year Rosberg has looked a shadow of the driver who more often than not was faster than anyone else in the F1 field, and who led much of the 2014 world championship.
The advantage in that battle eventually slipped through his fingers of course. But Rosberg came into this campaign determined to be better, faster and stronger than he was last year. He used the winter to focus on improving his weak points - namely too often conceding races from winning positions, while maintaining his strengths - chiefly a knack of often being faster than Hamilton on Saturdays.
