Amstel Gold was pretty amazing, but unless you heard differently, that was just tactics rather than any kind of 'deal'. Fuglsang played that one right - to win you have to risk losing.
Yeah, it's tactics but in the same vein where he says his legs are 'fu&ked' and wants someone else to pull more and then outsprints them in the end. This is a quote from Fuglsang:
“From when he attacked, I was still the one who was putting in the most effort because he always said that he was fucked. But he did the same at Strade Bianche, and there he still got me, so that's the game – that's the tactic."
