Days before his departure, the former Liverpool manager made an ultimatum to Moratti about transfers.
"Rafael Benitez did upset me towards the end," the oil baron said of the man he replaced on Christmas Eve with Leonardo.
"He is a Coach who constructs, but there was nothing to build here.
"He wasn't the ideal successor to Jose Mourinho, a tactician who deserves to return here because he was the best from the last 15 years.
"Leonardo? It's all going very well with him. All Coaches need a period to win and I think he'll be able to take advantage."
