We didn't see any particular surprises from today. Given that the track hasn't been used for quite a while and Formula 2 is the only support event, there was low grip, with a high degree of track evolution. We'd expect that evolution to continue throughout tomorrow as more rubber is laid down on the track. This year, we're bringing softer tyres than before, which obviously means that drivers have to manage their pace more carefully over the longer runs. As expected there was high wear on the soft compound, with some blistering seen on the front-left. Behind the Mercedes – which were particularly impressive on the harder compounds – the pace seems to be closely matched, and the performance gaps between the compounds suggests that many different strategies are possible. These strategies of course begin with qualifying tomorrow: it's going to be interesting to see which teams feel confident of getting through Q2 on the medium compound.
