Galliani was caught on camera screaming obscenities towards the goalkeeper after he conceded a soft opening goal in the 2-2 draw with Napoli on Saturday.
"As far as I am concerned, nothing has happened," the Italian said. "I didn't even know about it until Galliani phoned me.
"I know that Galliani loves me and we have a special relationship. He told me that it was all forgotten after just a second."
