The Portuguese head coach has struck a frustrated figure at Old Trafford in pre-season following a lack of top class signings in the summer transfer window.
Mourinho has signed Shakhtar Donetsk midfielder Fred, FC Porto defender Diogo Dalot and Stoke City goalkeeper Lee Grant to bolster his Manchester United squad.
The 55-year-old’s attitude in the media has attracted criticism ahead of Manchester United’s Premier League opener against Leicester City on Friday night.
Manchester United finished in second place in the Premier League table last season but ended up 19 points adrift of Pep Guardiola’s champions Manchester City.
The Red Devils ended the 2017-18 season without any silverware after Mourinho led Manchester United to the Europa League and the League Cup in his debut campaign at Old Trafford.
Former Liverpool FC defender Carragher leapt to the defence of the Manchester United boss ahead of their opening Premier League fixture against Leicester on Friday.
“I actually think Jose Mourinho hasn’t helped himself in this pre-season with the way things have happened but I do think he gets a little bit too much criticism, even for the job he’s done at Manchester United,” Carragher told Sky Sports.
“In his first season he won two trophies, not the Premier League or the Champions League trophies he will be judged on as a United manager but it’s very difficult now to win trophies with that top six being so competitive.
“Last season they were runners-up in the league and FA Cup runners-up and okay, that’s not good enough for Manchester United but I don’t think it’s as bad as people have painted it.”
Manchester United haven’t won the Premier League title since 2013 when Sir Alex Ferguson was still in charge of the Old Trafford outfit.
The Red Devils secured their best finish since the Ferguson era last term.
