Lopes pushed him back as clashes erupted between home fans and Lyon players.Lyon striker Alexandre Lacazette, who was rested for the game, took to Twitter to express his anger. “Pfff, shameful!!” Lacazette wrote. “Nonsense!!!!”Pfffff honteux !!!Nimporte quoi !!!! ????????- Alexandre Lacazette (@LacazetteAlex) April 16, 2017Speaking to L’Equipe TV, junior minister for sports Thierry Braillard condemned “unacceptable actions that will need to be sanctioned equally to their seriousness” and lamented a “bad day for French sports.”The first pitch invasion took place about 15 minutes before the end of the warmup at Armand Cesari stadium when supporters from the Bastia 1905 group of fans came on the field and jostled with Lyon players, including Memphis Depay and Mathieu Gorgelin.

The French league said in a statement that, after the first trouble, it had been decided that the match could go ahead but would be stopped if another incident happened.It was the second time this week that a Lyon game was marred by violence. Lyon is facing likely sanctions from UEFA after crowd disorder delayed its Europa League home quarterfinal against Besiktas midweek.Incidents inside Lyon’s stadium – which will host the final of the tournament next season – followed fighting among French and Turkish fans earlier in the city on Thursday. About 20 minutes before the scheduled kickoff, Lyon fans spilled onto the field for their own safety after fireworks were set off and missiles thrown from an upper section of the stadium housing Besiktas supporters. The game finally began 45 minutes late after police intervened in the stands.The French league said it would investigate the Bastia incidents and urged the club to ban the fans responsible.”The French league is asking Bastia to take all necessary measures in order to issue stadium bans against those responsible for these acts,” the league said. “And more generally to take all measures required to guarantee the security of matches played in its stadium.”In a statement issued a couple of hours after the match was abandoned, Bastia “firmly condemned” the vioence and said it would attend a disciplinary committee at the French league on Thursday.Last-placed Bastia, which has struggled the whole season, risks seeing its slim hopes of staying in the top flight hit by heavy sanctions, possibly including points deduction.Lyon is fourth, some 19 points behind third-placed Nice, and can’t secure a top-3 finish. Monaco tops the standings with a three-point lead over Paris Saint-Germain.
