Schmeichel was speaking on beIN Sports when he discussed what went wrong for Mourinho and why United had no choice but to part ways with the 56-year-old.
“I think the biggest problem that we had with him was the communication to the world," Schmeichel said.
“He represented Manchester United and it wasn't good. It was very negative and it was kind of really sort of sad in a way.
“There are millions of Manchester United fans everywhere in the world. A lot of them live by the club. They need to be inspired by the manager."
