Arnaud Demare triumphs in dramatic Milano-Torino

Manuele Boaro had been leading as the peloton entered the closing stages of the semi-classic when a huge crash led to a chaotic finish.

Peter Sagan opened the sprint but fell away and finished fourth, with Demare piloted by his Groupama-FDJ team-mates across the finish line.

Caleb Ewan finished second and Wout van Aert completed the podium spots.

"The calendar was a bit thrown out by the current situation, but it's good to be racing again and I had a very good return to competition at the Vuelta a Burgos," Demare said. "The team was very good, and we knew today was a good chance for us.

"We really know one another very well, and that's a good thing. We did a three-week camp and the whole team was in good form, Burgos confirmed that. We're not afraid of anyone. I feel very well."
