While the Williams is certainly competitive enough to win – last night was proof of that – I don’t think more victories are guaranteed. If it is going to happen, then they need to get everything right from the minute they arrive at the circuit to the moment the flag falls. If I had to guess where another victory might happen, I’d be inclined to say Singapore (since Maldonado was very good on street circuits in GP2), Korea or India. And I guess some of it depends on what they do with the second car. After speaking with Frank Williams, Mika Salo is apparently tipping Williams to replace Senna with Bottas very soon. I don’t think Senna has what it takes to win – far too many glaring errors – but if Bottas gets in the car and lives up to his potential, then I’d say he’s an outside (and a very outside at that) chance of a win.
As for Sauber, I don’t think they’ll win in Canada. Perez’s best results have come on circuits with higher downforce demands. Sepang is an aero-reliant circuit to begin with, and the rain just made it moreso. But I think the team is still a little inconcsistent to start talking about wins without some outside help, be it a collision at the front or wet weather. I’d certainly look for them to be strong at Monaco, Suzuka and Silverstone, though.
