Fourth definitely isn't a bad result - particularly considering I started from eighth. I ran as high as third during the first stint, but in hindsight it was probably an error to make our first pitstop so early. Both Kamui and I were compromised behind a Toro Rosso, and that cost both of us a bit of time to Felipe. He'd started on a brand-new set of tyres, and that makes a big difference: you can go longer and keep the speed up, so he was able to jump both of us after the first stops.
Towards the end, I was able to push and start catching Kamui. But he controlled his final set of tyres very well - I could get close to him, but the only way I was going to get into the DRS zone was by braking extra-late into the chicane, and, every time I tried, I locked up and ran wide.
Still, this result isn't too bad - we got some more points - we just didn't have the pace to go for the win today
