Koeman was surrounded by fans outside the Nou Camp after the defeat against Real Madrid.
The win helped Los Blancos create a new record, winning four Clasicos in a row in La Liga for the first time since 1965.
Following the defeat, Blaugrana manager Ronald Koeman faced the wrath of the fans as he was surrounded by them while trying to leave the Nou Camp in his car.
Barca have deemed fans’ behaviour as violent and insisted that they would take necessary measures to avoid such things in future.
The Blaugrana wrote on Twitter (h/t Goal): “FC Barcelona publicly condemns the violent and disdainful acts that our manager experienced when leaving the Camp Nou. The Club will take security and disciplinary measures so that such unfortunate events do not happen again.”
Koeman has found himself in the hot seat after Barca’s dreadful start to the season, currently ninth in the La Liga table. Furthermore, their form in the Champions League this season is even worse, suffering back to back defeats against Bayern Munich and Benfica before scrapping a win against Dynamo Kyiv.
There had been reports about a new manager succeeding Koeman but Barca president Joan Laporta insisted that the Dutch gaffer would continue.
Despite Laporta’s comments, the odds are against Koeman and he could lose his job if he fails to turn things around.
Barca can lose their place in the Champions League and top four of La Liga should their struggles continue.
