The 'wheelsucker' labels directed towards Lucien Van Impe and Joop Zoetemelk by Guillaume Driessens [nl] was a way of saying they did not attack to win and instead follow someone else who attacks to win.[162] Zoetemelk first gained the label after his second place to overall winner Eddy Merckx in the previous Tour, when it was joked that he was as pale as when he began the race because he was always riding in Merckx's shadow.[163][164]
The aggressive and bully-like nature of Eddy Merckx's directeur sportifGuillaume Driessens [nl] was not reserved solely for opposing riders. In fact, Merckx disliked Driessens before he was his directeur sportif. Specifically, Merckx did not like the manner in which Driessens would talk down to him and tell him what he was doing wrong when they were on opposing teams earlier in his career.[165]
