Los Blancos went above Barca after winning El Clasico at the Santiago Bernabeu on March 1, but the Catalan club returned to pole position after Zinedine Zidane's side then lost away to Real Betis.
Three days later, LaLiga was suspended due to the coronavirus pandemic with Barca two points ahead after 27 rounds of matches.
"If Madrid had finished as leaders before the confinement, LaLiga would have finished," the controversial former president told the Tertulia del 10 del Barça talk show.
Gaspart, who oversaw a dark period in Barca's history between 2000 and 2003 before he was replaced by Joan Laporta, also discussed the club's current problems.
"There's a lack of respect towards Barca and a lot of anti-Barcelona sentiment," he said.
And asked if he would like to see Neymar back at Camp Nou, he added: "I would love to see Neymar at Barca.
"I still think he has things to offer. I don't know the small print, but I would forgive him everything in order for him to return."
