Spectators invade pitch as Saint-Etienne relegated
STORY: One eyewitness inside the stadium filmed the moment fans were on the pitch.
The police used tear gas to disperse the crowd as the players went back to their respective dressing rooms after some supporters invaded the pitch and threw flares at the stands, French media reported.
The tie ended in a 2-2 aggregate draw after the second leg finished 1-1 at St Etienne's Geoffroy Guichard Stadium, before Auxerre won the shootout 5-4.
Auxerre will replace Saint-Etienne in the top tier, joining Toulouse and Ajaccio. Metz and Bordeaux were also relegated.
Saint-Etienne were forced to play behind closed doors earlier this month after fireworks were lit in the stands in a 4-1 home loss to Monaco in April, interrupting the game for almost half an hour.
