UPDATE.
Ferrari's Fernando Alonso was a surprise pace-setter in the first practice session of the new season as Lewis Hamilton hit trouble. Alonso was more than half a second quicker than McLaren's Jenson Button as pre-season favourite Hamilton's Mercedes broke down on his first serious lap. World champion Sebastian Vettel, who had a disastrous pre-season, was seventh fastest after just 10 laps in the Red Bull. The German's car failed on its way into the pits towards the end of the session. Finn Valtteri Bottas, tipped to compete at the front for Williams this weekend, was third fastest, ahead of team-mate Felipe Massa, Vettel's team-mate Daniel Ricciardo and the second Mercedes of Nico Rosberg.
If you don't want me to do updates after Practice because you haven't watched it yet, then let me know and I wont.
