Former Camp Nou chief has slammed the Portuguese coach following another night of fighting between the two historic rivals and an action-packed second lag clash
Mourinho appeared to hit out at Barca assistant coach Tito Vilanova as the touchline tension reached boiling point after Marcelo was shown a straight red for a wild lunge on Cesc Fabregas.
Pep Guardiola's men won 3-2 on the night (5-4 on aggregate) and Gaspart has questioned Mourinho's behaviour during the touchline brawl.
"Mourinho has a double personality," Gaspart told COM Radio.
"He transforms himself when it comes to football, but this is not his normal way of being. Even Madrid seem happy with it, but I really do not understand this.
"He is not the Mourinho that I have known."
Speaking of the coach's attack on Vilanova, Gaspart said: "This is not normal. I can never remember a coach attacking another."
Reports in Spain suggest Barcelona will not submit a complaint to the authorities over Mourinho's behaviour following the mass brawl which broke out, but this has not been confirmed officially.
