That’s the view of Liverpool legend Jamie Carragher.
United held Liverpool to a 0-0 draw at Anfield on Saturday afternoon.
Mourinho’s men had just one shot on target during the highly-anticipated affair.
The Special One has not won in his last 10 away games against a top-six Premier League side.
And Carragher says Mourinho must improve that record if United are to beat Manchester City to the title.
Carragher told Sky Sports: ”Jose Mourinho has always been lauded - and rightly so - as the man for the big occasion, the man in a big game, a 'Mourinho masterclass' winning these games.
"His way, of late, is not working.
"I go back to when Peter Schmeichel was winning titles with Manchester United and they possibly had six big games - Liverpool home and away, Arsenal home and away and someone else challenging, whether it was Chelsea or Newcastle.
"That's 18 points. With the top six now that's 30 points. That's a big part of the season. You've got 10 games home and away.
"If that doesn't improve they won't win the league and that's when the criticism will come.
"I won't criticise him for the way he played at Anfield because you can still win a game playing like that - but if those results continue I think it will be very difficult to win the title."
