I think this will be Alonso's best chance to get another victory. With that Ferrari engine being immense, and the track being Redbull's achilles heel.
Probably, but if it rains it can even out the playing field a bit. Vettel has won here twice, the first time in the rain in a Toro Rosso.
Fast, low downforce tracks have been Red Bull's weaknesses but they set it right at Spa with that lower downforce setting that blew everyone, Alonso included, off the track. Also, vettel was the fastest over the speed traps, something new for him and Red Bull. If they get the set-up right for Monza, Vettel has a good chance of beating Alonso.
I don't think anyone will catch Vettel to the WDC but I have a feeling that Hamilton and maybe Raikkonen will catch and pass Alonso. With the exception of Suzuka, Ferrari might struggle on the other 'Eastern' tracks like Singapore, Korea, India and Abu Dhabi.
