Elia Viviani handed Deceuninck - Quick-Step their second win in as many days at the Tour de France by sprinting to a dominant victory on stage four in Nancy.

Viviani profited from a perfect lead-out to beat Alexander Kristoff (UAE Team Emirates) into second place and Caleb Ewan (Lotto Soudal) into third.

Viviani’s team-mate Julian Alaphilippe, who won stage three solo, retained his 20-second lead at the top of the general classification over second-placed Wout Van Aert (Team Jumbo-Visma).

Viviani’s victory means he has now won stages of all three Grand Tours.
