Dan Martin. And Fuglsang is the current champion of both.I agree with you Tonton that never having gone for the Ardennes classics is a missed opportunity as LBL especially is within his skill set for sure and to win both climbers monuments would really elevate his status in the sport in terms of overall palmares.
Has anyone won both in their career in the last 15 years other than Gilbert?
Bettini's last Liege win was 18 years ago, but he last won Lombardia in '06, so he just gets in.
Might as well throw the other names back to the 80s; Camenzind, Bartoli, Richard, Argentin, Kelly, Hinault. Before that, you get into Merckx and deVlaeminck, and like approaching a black hole the laws of physics no longer apply.
