The Portuguese said it was due to United’s fragility in defence.
Mourinho’s side travel to Burnley on Sunday after two consecutive defeats in the Premier League.
The former Chelsea manager’s playing style has been widely criticised by football pundits but the 55-year-old insisted his defence needs to be better in order for United’s attack to improve
“We will try. We are going to try, you know,” Mourinho told press conference ahead of Burnley clash.
“It’s a process that has risks especially if you make the defensive mistakes that breaks that dynamic
“The teams that are really, really good offensively are the teams that are very, very solid from the back.”
Asked if United can play like City or Liverpool, “They play the way they play, and we play the way we play.
“I don’t even want to try to say something in relation to that.
“They are what they are and we are what we are.
“Against Tottenham, we were really positive and really strong and I think the opponent, a very good opponent, felt that and felt they were really in trouble.
“But two defensive mistakes in five minutes lost the game for us.”
