Okay, thank you for that. Adrian, your thoughts on today? Obviously, you and Ferrari look very quick but as Nik was saying it's not always easy to draw conclusions from Friday. However, do you see it being a scrap between the two of you this weekend?
Well, If Nik would be kind us enough to tell us what his fuel load was this afternoon we'd have a better idea, but he probably won't do that so, no, as Nik says then it's certainly tight with Ferrari. Lotus I'm sure will be good, we've seen they have very good tyre degradation, and Mercedes are the outsiders I guess, so it's the usual story of the last few races.
Obviously Red Bull was one of the teams calling for a change to the tyre specifications. Pirelli has made one change, to the hard tyre that we have here this weekend. That was the preferred tyre here in the race last season. Can you give us your take on the changes that have been made? Did it go far enough as far as you're concerned?
The changes to the tyre relative to last year are two-fold, one has been construction and the other has been compound. As you say they've gone back to the compound that we used in some of the races last year but that still leaves a very significant construction change, so it's still a very different tyre to what we had last year.
Moving on to Dave Greenwood from Marussia. Obviously Marussia have taken a clear step forward this year in performance. Can you quantify it for us and tell us where the major gains have come from?
Well, it's difficult to put exact numbers on it but definitely we're a per cent or so closer to the front. We no longer worry about anything like 107 per cent, those days are long gone, so it's much more looking towards the midfield, where we want to go. Obviously, as anyone else would say, the main advantage has come in aerodynamics – better correlation in the wind tunnel – and perhaps slightly more creativity in that area. That's where really most of the lap time has come, coupled with improvements in the mechanical installation of course.
We spoke earlier about the possibility of in-season testing returning. As one of the teams with a smaller budget how would feel about that?
It's a tricky one isn't it? As an engineer you'd want to go testing but obviously there's a resource issue there to consider as well. I think as Nikolas said, it's probably one more for the team principals. But I think for us it would be as long as it was in a measured, controlled way and not an absolute free-for-all then maybe it would be something that would enable us to slightly catch up by having a little bit more testing.
Moving on to Andrew. Obviously, first of all, we have to start by asking about Paul Di Resta's left-rear tyre failure. What can you tell us about that from second practice this afternoon?
Well, completely unexpected, in the middle of a high-fuel run, it was on about lap six or seven. That's all we know at the moment. It's currently under investigation by Pirelli and I'm sure they'll release something as soon as they know but it's early days yet.
