We knew pretty quickly where the performance deltas were and where we were weak. I think we’ve talked about those and we wouldn’t talk about them in huge detail anyway.

But it’s obviously to anybody that, with Formula 1 being such an aero-dominated sport anyway, we’re down on downforce and we need to do more work to achieve that. We went through a huge change in aero last year, bringing in a new chief aerodynamicist in Doug McKiernan who brought in a new philosophy to how we go about bringing aero performance to the car.

When you do that inevitably it’s going to take some time to bed in. You almost go back to basic principles which is what, in effect, the whole of aero did last year and they needed some more time. We are now seeing our aero performance curve go on an upward trajectory which is really good to see. That will come out over the next few races.

Then there have been some mechanical issues again which I think people are fully aware of that we are working hard to resolve. The majority of which we have resolved.

Everyone is working hard at Williams and I finally feel that we are starting to see some green shoots of progress. And we really are seeing that.
