After today's 2-2 draw with Burnley at Old Trafford - in which they were rescued by Jesse Lingard after Zlatan Ibrahimovic stirred discomfiting memories of Falcao - Mourinho told the press that United are not true title contenders as they have not spent enough money.
Mourinho insists that he has no problems with the performances of his players, but did concede that his side have been letting in too many easy goals of late.
Despite signing Romelu Lukaku, Nemanja Matic and Victor Lindelof for a combined total of around £146 million (S$262.4 million), the United manager still thinks his squad lack the quality to compete with the likes of Manchester City.
Lingard came off the bench to flick home and give his side a lifeline, and Burnley were denied a first away league win over United since September 1962 when the England worldwide fired home in second-half injury-time.
"We are in the second year of trying to rebuild a football team you know is not one of the best teams in the world", said Mourinho, after the tepid 2-2 home draw with Burnley, with City's 1-0 win at Newcastle taking them 15 points clear at the top.

A member of the press followed up pointing out that Mourinho has spent £300 million as United manager.
It is two more dropped points and a further example of just how far the rest of the league is behind Manchester City, but more than that it was a lesson for Mourinho to learn. The price for the big clubs is different than for the other clubs. "So when you speak about big football clubs, you are speaking about the history of the club".
"The boys do what they can".
"I am not happy with the result, I was not happy with the result against Leicester, but I am happy with my players".
