The fact that we've seen quicker lap times than last year despite nominating tyres that are a step harder shows that this was the correct selection for Sochi, in what is very likely to be a one-stop race. Having three different teams in the top three FP2 times, with Ferrari going quickest in the morning and Red Bull fastest in the afternoon, underlines how closely matched the teams are in terms of pace. However, the weekend's action is set to be heavily influenced by the weather, with rain expected tonight that could persist until tomorrow, before a dry race on Sunday. This meant that the teams focussed on collecting as much data as possible today, running all three compounds at length. Each one of them could play an important part in the race, depending on the strategy chosen.
