The clash ended in controversy when Mourinho appeared to put a finger in the eye of Barca assistant Tito Vilanova during a melee in the closing stages of the tie, which saw Barca emerge 3-2 winners on the night to claim the Supercopa 5-4 on aggregate.
Vilanova responded by striking the Portuguese on the side of the head as another meeting between the two Spanish superpowers ended on a sour note following last season's similarly ill-tempered Champions League semi-final ties.
Speaking about the incident today, Barca president Sandro Rosell explained why Barca had not lodged a complaint to the Spanish football authorities against Mourinho's behaviour.
"There are several reasons, the main one is that we need to stop this atmosphere of extreme tension," Rosell was quoted as saying by the Spanish press.
"There was a consensus among the technical staff and (sporting director Andoni) Zubizarreta not to report the actions of Mourinho.
"To report Mourinho could have affected the team's preparation (for Friday's UEFA Super Cup against Porto) and it was Tito Vilanova who asked us to forget the matter."
Rosell added: "The federation and the committees, if they want, must act off their own initiative. Barca will not ask them. What we have to do is forget this business."
