Eddy Merckx

Merckx won 19 monuments, including seven Milan-San Remos and five Liège-Bastogne-Lièges, alongside three Roubaix and two Flanders titles. No one else has won so often on such different terrain, from the flat run-in to San Remo to the long Ardennes climbs, and the sheer range is the point: he could attack anywhere.
