The Portuguese lashed out at faux experts passing judgement on his side and his career record of success based on a bad week.
Jose Mourinho has hit out at "football Einsteins" who he claims have tried to dismiss his career triumphs during a difficult week for Manchester United.
United beat Northampton Town 3-1 on Wednesday to move into the fourth round of the EFL Cup and end a run of three consecutive defeats against Manchester City, Feyenoord and Watford.
Mourinho conceded afterwards that the club's supporters were justifiably upset at the manner of those losses, with question marks existing over his continued selection of Wayne Rooney.
