Van Aert point the finger to Sagan last year, if I remember correctly, although it was a different fingerSeems like a fair call. However, this is probably the first time i have ever seen Van Aert deviate from his line, as he is one of the few who usually sprints dead straight. If they could ever make an exception, it would be for him. Funny though that Sagan of all people is the one to point the finger, literally.
Maybe Van Aert's deviation has something to do with Sagan being the rider who tried to pass him...
