Ferrari's Fernando Alonso is the man to beat after Friday practice ahead of the Belgian Grand Prix. Alonso, posting the fastest time at a wet track in Spa, as he looks to continue Ferrari's dominance of the event.
Sebastian Vettel led the Red Bull charge with a time of 1 minutes 49.689 seconds, but going out on a sightly wetter track than most, could only come sixth fastest while teammate Mark Webber could only go eighteenth fastest on his 34th birthday.

Robert Kubica was fourth fastest in the F-ducted Renault with a time of 1 minute 49.282 seconds.

Force India also showed they will be a power in Belgium as Adrian Sutil posted the second fastest time in a time of 1 minute 49.157 seconds.
