I have trouble seeing past vdP unless he gets dropped or he comes in with a large group at the finish. I think he is beatable by select people from a small group, but the strategies likely to be used will just play to his favor. Wait too long, his acceleration will catch them. Hammer along at full speed, he can sit on (and no one will want to tow him to the line).
I suspect he tries 1 x thermonuclear on the Poggio and will see if that's enough to crack loose, then relying on a small group sprint. His hope would be someone comes with him, otherwise he risks getting caught ... not sure he can hold everyone off (I don't think he has any team mates folks will be worried about towing?)
Guaranteed if Ala can go with him, he will, but I doubt he'll have a winning sprint. I think WvA would need to rely on this being a full speed sprint, and I'm sceptical either Ala or vdP will position themselves to lead him out.
Small chance if WvA can get a gap he does a Fabian.
