The 67-year-old Catalan occupied the top job at Camp Nou for three years between July 2000 and February 2003, and has admitted that he was never warmly greeted by Madrid officials.
"I will watch the game at home," he told COM Radio. "I have nothing to gain by going to the Santiago Bernabeu, where they insult me. It is a very much a madridista box."
And Gaspart added that the atmosphere in the crowd has now spilled over into the executive boxes.
"Now the fanatics, the passion and the rudeness has moved to the boxes," he said.
Reflecting further upon his tenure at Barcelona, Gaspart revealed that he still holds a grudge against former Camp Nou favorite Luis Figo for leaving the club in 2000 to join Madrid.
"I will never forgive him for going to Real Madrid,” he explained. "It was a move made with malice."
Gaspart had served as vice-president to Josep Lluis Nunez before taking over shortly before Figo’s departure and was heavily criticized for squandering the money received from that deal on Arsenal duo Marc Overmars and Emmanuel Petit, among others.
