The Weather: We'll start with the obvious. After all 4 sessions being affected by rain, the teams will have to be on high alert with their rain radars and the sky above as they try and keep tabs on any showers which may break out during the race. Tyre choice will be critical and a lot of tyre have been used up already.
La Source: 23 cars scrambling towards this tight corner should provide much activity and with all the drivers warned about taking to the run off area on the outside it may well get too tight for some...
Overtaking: Once the first corner drama has passed and depending on the order, get your eyes set to see who takes Eau Rouge well. Mark Webber is in a car which weakness is straight line speed and running on a full tank of fuel. Lewis Hamilton will want to utilise his F-Duct and make a move on the Australian. Robert Kubica is also flying on the straights and will be on the attack. Sebastian Vettel may need to beaware of Jenson Button as well.
Setups: It appears that Fernando Alonso's sluggish ace today was due to opting for a wet setup. A risk certainly if rain fails to materalise. We seen how this tactic can pay dividends in Brazil last year so Alonso, along with the Toro Rosso drivers will hope to wake up and hear the rain in the morning.
Drivers on a mission: Vitaly Petrov's qualifying lasted less than a la and was a mistake which could prove costly as his future remains in the balance. He desperately needs a strong drive tomorrow. He is helped that he can start from the pits and have free reign on setup and tyres as well as the F-Duct so watch put for him moving through the field. The Saubers and Mercedes will also be looking for progress as they find themselves behind the likes of the Lotus team.
It was a thrilling qualifying and should be an enjoyable race. Start time is 1PM UK time. Check out http://twitter.com/cmckinleyF1 for updates and views during the race
