Fernando Alonso and Jenson Button in 11th and 14th respectively, with two minutes left. Bottas also outside the top 10 and he's currently trying one more flying lap.
Raikkonen has also just spun off the track, down at turn 11. One tiny slip and there's trouble here today. We could have an amazing Q3.

Kimi Raikkonen and Sebastian Vettel have just gone quicker - they're the first two cars under two minutes... but moments later, Rosberg and Hamilton go a little quicker.
