Di Gregorio and to a lesser extent Brice Feillu. Feillu showed great promise with his TdF stage win but after that has had problems, but seems to be making a bit of a comeback.
Di Gregorio was greatly touted to be the next French TdF winner and showed great climbing promise in Catalunya in that mountain time trial in his first year as a pro. He has had some decent results like a Paris-Nice stage win but hasn't certainly lived up to the expectations. Veikkanen who was his team mate at FDJ said that he's a bit lazy, especially during off-season and that has hindered his career.
