Riders who win in Liège are what we call fondisti - men with a superior level of stamina. [The climb of] La Redoute is like the Mur de Huy in that it has to be tackled at pace, from the front of the peloton. The gradient is about 14 or 15 per cent, and it comes after 220 or 230 kilometers, so you don't have to be a genius to work out how tough it is. I remember that we used to go up with a maximum of 39 x 21 - it's not quite as steep as the Mur de Huy. A lot of riders mistakenly think you should attack on the hardest part, but in reality you hurt people on the slightly flatter section that comes after this.
