Saint-Etienne fans stormed the pitch in troubling scenes after a penalty shootout defeat to Auxerre confirmed their relegation from Ligue 1 on Sunday.

The Ligue 1-Ligue 2 play-off at Stade Geoffroy-Guichard ended 1-1 on the night and 2-2 on aggregate, with Hamza Sakhi's 51st-minute strike for Auxerre cancelled out by Mahdi Camara and extra time failing to produce a winner.

Ryad Boudebouz missed the first spot-kick of the shoot-out and that proved costly as Auxerre went on to triumph 5-4 and secure their spot back in the top flight.

The winning penalty was taken by Auxerre captain Birama Toure and preceded home supporters storming the pitch in frightening scenes, with flares and smoke bombs launched in the direction of the turf, with reports some were also thrown towards the directors' boxes.

Some fans also appeared to target Saint-Etienne players on a regrettable night for the joint-most successful club in Ligue 1 history, who have won the title 10 times – the same amount as Paris Saint-Germain.
