The Spaniard, whose Barca contract runs out at the end of the season, has been linked with a move to San Siro as Nerazzurri boss Claudio Ranieri comes under increasing pressure.
"He could surely come to Inter, but he would require time, which is something that Inter do not give to coaches," Corioni told Sky Sport Italia.
"You cannot expect Inter to play like his Barca all of a sudden.
"In my opinion, however, he will stay at Camp Nou for a long time."
Corioni then stated that he believes Inter made a big mistake when they sold midfielder Andrea Pirlo, who started his career at Brescia, to AC Milan in 2001, as the 32-year-old became an icon at their cross-city rivals.
"I called Massimo [Moratti, Inter president] and I told him that I had a very young phenomenon who no one knew and I asked him if he wanted the player," he explained.
"He told me to wait a few days to think it over. After a couple of days he called me and signed the player.
"At Inter, however, Pirlo was unsucessful and he joined Milan in a part-exchange deal with Guly.
"This deal made Moratti lose at least €100 million. He could not make his mark there, he played for Reginna before returning to Brescia on loan."
