Sort of
On a serious not I don't see why he can't out sprint Nibali for example, or Bernal, or even tired Valverde. Stranger things happened, we saw last Sunday something similar.
The difference is that Mads Pedersen is very fast and often has the role of a leadout man whereas Fuglsang is sort of a slug.
I also think that he would have a fair chance of beating Nibali or even Bernal, should it come to that, but certainly not Valverde even if his sprint seems to have deteriorated a bit over the last year.
How Fuglsang managed to beat Alaphilippe in Amstel is still a mystery to me and I have to see something similar happen again for me to actually believe that he can do stuff like that.
