A 1-1 draw with West Ham United on Sunday left United 11 points behind leaders Chelsea and without a win in four league matches at Old Trafford for the first time since 1990.
That dry home spell came toward the end of a 26-year title drought which ended in 1993 with Alex Ferguson collecting the Premier League trophy.
Ferguson retired in 2013 with 13 title triumphs to his name and Mourinho was appointed to recreate the Scot’s winning mentality at the club after three lackluster years under David Moyes and Louis van Gaal.
The only current similarity between Ferguson and Mourinho, who was fired a year ago by Chelsea, is the fiery temper on the Old Trafford touchline. At least with Ferguson it produced results.
Mourinho was sent to the stands for the second time in a month on Sunday after being enraged by Paul Pogba being booked for an apparent dive and kicking a water bottle.
At the end of last month the Portuguese was dismissed for abusing referee Mark Clattenburg at halftime against Burnley.
Jon Moss, the referee, had history with Mourinho, having also sent him to the stands against West Ham for a halftime rant at the official when he was Chelsea boss last November.
