Moratti has explained to fans why he went for the former Liverpool manager.
He told Inter's website: "Rafa will be unveiled on Tuesday and we will begin to speak about the market on Tuesday.
"We chose him because we thought that he could guarantee us the future. I hope that this happens. Rafa is very serious, a great worker and that is the principal thing.
"From a human point of view, he seems to be a rich person, who has different characteristics from Mourinho, but this is also important because I said that I didn't want a Mourinho impersonator.
"I wanted someone who has their own characteristics, their own personality and Rafa has just that."
