Benitez has been linked with the job to replace Jose Mourinho, since the Spaniard was sacked at Liverpool last week.
“The deal for Benitez in its final phase… A signature today? Maybe, yes… you would have to ask [Marco] Branca,” Moratti told Sky Sport Italia.
La Gazzetta dello Sports report that Benitez has agreed to a three-year deal worth around €5million per year.
