Lewis Hamilton's victory ahead of Valtteri Bottas in the Chinese Grand Prix means Mercedes has started what should be its most challenging season in years with a hat-trick of one-twos. But Formula 1's 1000th race wasn't just about the Silver Arrows dominating, it also cruelly exposed three key weaknesses for a chastened Ferrari team.
Firstly, Ferrari was not fast enough in China, even with its straightline speed advantage carrying over from Bahrain. Secondly, Ferrari was indecisive in how it managed its drivers and should have either ordered Sebastian Vettel past Charles Leclerc earlier or let the battle between the pair play out rather than doing a bit of both. Thirdly, its strategy with Leclerc was questionable, ultimately costing him any chance of beating Max Verstappen to fourth place.
Ferrari's pace in Bahrain had raised hopes for the team but, with Mercedes convinced it had run a little too much wing and therefore drag there, things were back to what we now must consider normal in China. The best of the Ferraris was three tenths of a second down in qualifying as Bottas and Hamilton locked out the front row.
