Ronald Koeman claimed the unsavoury scenes as he left Camp Nou after the defeat against Real Madrid reflect greater social issues.
Barcelona sit ninth in LaLiga after a 2-1 loss to Real Madrid on Sunday, Koeman becoming just the second coach to suffer defeat in his first three Clasico meetings.
The Blaugrana also made it five wins without a LaLiga Clasico victory, their longest winless run against any team in the Spanish top flight since May 2008.
After the game at Camp Nou at the weekend, under-fire Barca boss Koeman had his car mobbed by a crowd of fans as he attempted to depart the stadium.
The Catalan club released a statement to condemn those actions and Koeman suggested the incident reflected wider problems as he prepares to face Rayo Vallecano on Wednesday.
I don t think there is a solution, Koeman told reporters at Tuesday s pre-match news conference.
For me, it is more a social problem, it is not a matter of them being Catalans. It is more a matter of education, they have no values.
We don t have to pay much attention, and it seems that it was only with me, but it has been with many players, with their families.
It may be that with me it has been more exaggerated, but even Carles Puyol had to suffer.
The club knows that this cannot be repeated and has to find another formula. It should not be given more attention, it is a social problem that happens all over the world, not just here.
