I am really pleased with my performance today. I think we got as much out of the car as we could and the fact we were on the same lap as the leaders right up until the final lap is a very positive sign. We brought some updates here and they've worked out pretty well - the key for us is to keep pushing, keep bringing new parts to the car and make sure we maintain the momentum we are building up.

I had a good start, getting up to 16th off the line and then was running pretty well for the first stint on the options. We pitted on lap 13 and went to the primes which held up well until lap 30 but then as soon as we made the second stop I could feel an issue with the right rear so we had to stop again immediately which was basically the end of my race. This hasn't been our strongest weekend but with the next race back-to-back with China we can look to bounce back straight away, so we'll regroup in Bahrain and look to put in a stronger weekend there.

Today's race was pretty tough, but I am pleased with the way both drivers kept pushing and I think we have learnt some very useful lessons here in China. We opted to start both cars on the soft tyres and our pace in the early laps was good. Both drivers switched to the medium compounds for their second stops and we were easily pulling away from the cars behind but then when Heikki stopped on lap 30 he felt a problem with the rear of the car as soon as he pulled out of the pitlane so had to do a very slow lap and come back in. Vitaly had a problem free afternoon and was putting in good lap times, staying on the lead lap until almost the final lap and with every race he is growing more and more confident in the car and with the team. Now we have another week of hard work ahead of us so we will do our best to make the most of the different conditions we will face in Bahrain and aim to get back to where we know we should be.
