The Nerazzurri slipped to eighth in Serie A over the weekend, 10 points outside the Champions League qualifying places, prompting Moratti to remove current boss Claudio Ranieri from his position and put Primavera boss Andrea Stramaccioni in charge on a temporary basis until the end of the current campaign.
The Inter chief has copped a lot of flak over the past few days for the way in which he is running the club but he feels that Gasperini, who was sacked last September, is to blame for their current predicament.
"I am not at all satisfied with what Gasperini did," Moratti told Sky Sport24. "The responsibility for this underwhelming season lies mostly with him."
Moratti admitted that he is now hoping that Stramaccioni can inspire a rapid improvement in the first team's fortunes - despite having no previous top-flight coaching experience.
"Stramaccioni has talent and is very good from a tactical perspective, so anything could happen," he opined.
"I hope that actually he could be a solution for the future. If he wins all his games, I could hold on to him.
"In terms of European qualification, I hope we can do it but I don't believe we can and the failure to qualify would be a big problem for us.
"His arrival is a good thing, at least we awake in the morning with a fresh atmosphere [around the club]."
However, Moratti then appeared to undermine his new coach but confessing his admiration for a number of men who have been linked with a summer switch to San Siro.
"[Athletic Bilbao's Marcelo] Bielsa is a great coach, like [Catania's Vincenzo] Montella and [Pescara's Zdenek] Zeman," he mused. "But I speak well of a lot of coaches.
Then turning his attention to the playing staff, Moratti conceded that injury-prone striker Diego Forlan has not proven an adequate replacement for Samuel Eto'o, who was sold to Anzhi Makhachkala last summer.
"Forlan has played only a little, but badly," the Inter president said of a forward who cost the Nerazzurri a reported €5 million.
Stramaccioni's first game at the helm comes against Genoa at the Giuseppe Meazza this weekend.
