Mourinho’s troops are five points behind fourth-placed Chelsea and trail pace-setters Manchester City and Liverpool by 15 and 16 points.
United have been widely criticised for their poor displays this season, which have raised serious doubts over Mourinho’s future at Old Trafford.
Mourinho himself has arguably been United’s biggest critic, though he is proud of how his side keep battling back from adversity when they go behind.
“Nobody can deny these players have guts,” the Portuguese said in programme notes ahead of today’s game with Fulham.
“At the moment, it seems like every game we play, we go behind, but we keep coming back.
“Time after time this season, we have made things hard for ourselves.
“We keep shooting ourselves with our mistakes, which is a big part of the reason we are where we are in the Premier League table.”
United got back to winning ways earlier this afternoon with a 4-1 win over league strugglers Fulham.
Victory over Claudio Ranieri’s side was United’s first league win in over a month.
Mourinho will be hoping his men will continue their good form on Wednesday night when they travel to the Mestalla to take on Valencia in their final Champions League group game.
United have already sealed passage to the last sixteen of Europe’s elite club competition but will be looking to steal top spot from group leaders Juventus.
