It is a very big change. On a day-to-day weekend in F2 and F3 you’re just changing a few things. You’re very limited in what you can change: roll bars and wing angles and so on.

When you get to F1 it’s a very different story. Every weekend there’s normally a reiteration of some part or another which will affect certain things.

So we always need to keep in mind how things are going to develop into the future and that affects quite often how one weekend will go. You’ll have one focus set on a certain thing at one race track, you get to the next one and it’ll be the complete opposite because you’ve got a new part or a new rear wing or something like that. And it is quite different because a lot of the stuff I say and Carlos says leads everyone in a direction and if we say we’re complaining or some things and therefore it leads the aerodynamicists and engineers down a certain path and they start looking at things to improve that area and then you get to the next track and maybe it’ll change and it’ll be the opposite.

So you have to be quite Norris: careful we’re not saying ‘right,all I need on the car for next year is X’ but look at the bigger picture and think ‘if we have this or that, the whole package will improve’ rather than one specific thing.

I got much better at that last year. Especially at the beginning I was shy, let’s say, to say anything too much because I didn’t want to lead anyone in the wrong direction and say things which maybe weren’t necessarily true. But as I went through the season, especially towards the end I was more confident in saying ‘this is what I need and this is what I want, and next year if I have this or that I can do a better job’.
