The biggest problem for Madouas, more than in probably any other race, is his almost Cort'esque inability to position himself in a peloton.
Many a race he is easily one of the strongest 3-4 riders, but spend most his energy making up his own tactical mistakes.
If he had the same "racing nose" and toughness in fight for position, that Küng has, he would be a serious contender for the big cobbled races.
Poor positioning isn't bad tactics.
