WATCH - Nabil Fekir goads rival fans with 'Messi' celebration sparking pitch invasion of furious Saint Etienne fans
From Patrice Evra's kung fu kick to Mario Balotelli punching a dugout, it has been a tempestuous few weeks in Ligue 1 - and Nabil Fekir caused more dramatic scenes with a provocative celebration.
Fekir scored the fifth goal in Lyon's resounding 5-0 victory at fierce rivals Saint Etienne, and celebrated by holding his shirt up to the home fans.
The routine mimicked Lionel Messi's famous celebration after scoring a late winner in El Clasico, when he held his shirt aloft at the Santiago Bernabeu. Ronaldinho, Cristiano Ronaldo and Mauro Icardi are among other players to have done the same.
Saint Etienne's supporters were incensed and rushed onto the pitch, causing riot police to intervene and the match to be temporarily suspended with just five minutes remaining.
Play resumed in front of a near-empty stadium, although the result was by then a foregone conclusion as Lyon moved into third behind Monaco and Paris Saint-Germain. Fekir however, refused to apologise.
"It's a gesture they did not like," he told Canal+. "I celebrated like that. There was no ulterior motive, no malice.
"Maybe it's not the right move to make – it was 5-0 – but it's still football. I was a little upset. It added a bit of spice, too. There was no need for [the reaction].
"I do not regret the gesture."
Elsewhere in France, former Manchester City striker Balotelli scored and was sent off in Nice's 1-0 win over Dijon.
The Italian saw red for a reckless challenge near the end of the game and took his frustrations out on the dugout, punching the bench and startling an unsuspecting club official.
Balotelli had an impressive first season at Nice alongside Hatem Ben Arfa as they qualified for the Europa League, but they have won only four of their first 12 league games this term.
