Riot police clash with pitch-invading fans as Saint-Étienne relegated from Ligue 1

Their defeat was greeted by a pitch invasion by angry Saint-Étienne fans and the intervention of French police who used tear gas to stem the trouble.

Saint-Étienne, who finished third from bottom in Ligue 1, had already drawn the first leg of their play-off 1-1 with Ligue 2's Auxerre.

Sunday's second leg at their Stade Geoffroy-Guichard also ended 1-1 with Saint-Étienne's Mahdi Camara cancelling out Hamza Sakhi's opener.

With the scores 2-2, the tie went into a penalty shoot-out which Auxerre edged 5-4 with goalkeeper Donovan Léon making a crucial save to deny Ryad Boudebou.

As soon as Birama Touré converted the final penalty to win the tie, Saint-Étienne fans invaded the pitch and threw flares towards the official stand.

The players of both teams took refuge in the changing rooms but Prime Video television footage from the tunnel showed players, stewards and staff coughing from tear gas used by the police on the pitch to disperse the invaders.

Saint-Étienne have already been sanctioned several times this season for the behaviour of its supporters and this game was played with one stand closed following incidents during the match against Monaco at the end of April.

The result marks the end of a nightmarish season for the 10-time French champions who are now facing serious financial difficulties as they return to Ligue 2 for the first time since gaining promotion in 2004.

France's sports ministry on Monday will host a meeting of security and football officials following the chaos that marred the Champions League final between Liverpool and Real Madrid, as Paris prepares to host the 2024 Summer Olympics.
