Blaugrana president Sandro Rosell claims "people would go crazy" if his side sanctioned the level of spending enjoyed by rival Real Madrid this summer.
The Wales international secured his protracted move to Estadio Santiago Bernabeu shortly before the end of the summer transfer window, though the sum involved has attracted significant criticism, with Barca coach Gerardo Martino claiming it showed "a lack of respect for the world we live in."
While Rosell admits the timing of Martino's comments was ill-advised, he has voiced his own disdain for the world-record fee, claiming that his own club could never match such sums on a single player.
"I wouldn’t have paid 100 million euros [for Bale]," Rosell told TV3. "Barcelona cannot allow for that. If we pay 100 million, people would go crazy. Madrid is a private institution and if their socios allow it, then I have nothing to say.
"We need to tell Tata that he can’t always say what he thinks, but he was speaking from the heart."
Rosell was quick to praise Madrid for its decision to allow Kaka to return to AC Milan on a free transfer, however, stating that the departure of the likes of the Brazilian and David Villa from Camp Nou are useful in freeing up the wage bill.
"Madrid selling Kaka to Milan for nothing was a good move. That’s one huge salary off the books at least. Just like selling Villa was a good move for us," Rosell said.
Rosell also revealed he has been in touch with Tito Vilanova, who is continuing to battle cancer following his relapse earlier this year.
"I had dinner with him the other day and he looked well. He’s fighting, he’s putting all his energy into it and I hope he comes out alright on the other side," Rosell said.
