Wright senses the United support are turning on Mourinho.
"The football United are playing is nowhere near what the fans identify with and demand," Wright wrote in The Sun.
"The love between the stands and the man in the dugout just doesn't seem to be there.
"I'm not saying Jose doesn't have the supporters' backing but you don't get the impression it's a deep-rooted affection.
"The situation isn't at crisis point yet but Jose has to ensure any cracks don't become chasms. If they turn into full-blown rifts, it can only end one way — in tears."
