Tour de France: Elia Viviani waiting for his opportunity

Cannondale's Italian sprinter Elia Viviani has been a key cog in the lead-out train for Peter Sagan at the Tour de France with the team goal of securing a third straight green jersey in Paris. Having been given free rein in the Giro d'Italia sprints in May, Viviani has been playing the domestique role during July but is hopeful of getting his own opportunities later in the race.
