We saw two busy, exciting and very closely-matched sessions, with three teams in the top three places after each practice hour. From the perspective of the tyres, we're satisfied with the performance, which is very much what we expected with plenty of recent testing in Bahrain. Teams focussed their work on the C4 soft tyre in particular, having already collected a lot of data on the C2 and C3 compounds two weeks ago during testing. The performance gap between medium and soft is a little higher here than we initially thought, while C2 and C3 are very close. This means that all the tyres can play a key role in the race.
