LYON, France - Olympique Lyonnais fans tried to invade the Groupama Stadium pitch in ugly scenes after their side were knocked out of the Europa League following a 3-0 defeat by West Ham United on Thursday. Dozens of supporters pushed the safety barriers that were held by stewards after the final whistle following the London side's 4-1 aggregate victory. France's Ligue 1 has been hit by a spate of fan violence this season and a Lyon game was called off in December after Olympique de Marseille's Dimitri Payet had been hit by a bottle thrown from the stands.
