The Red Devils have endured a stuttering start to the season under new boss Mourinho and are currently in sixth place in the Premier League table.
Mourinho has been tasked with steering the Red Devils back into the Champions League this season following their fifth-placed finish under Louis van Gaal last term.
Manchester United have been criticised for their lack of ruthlessness in front of goal this season and were held to a goalless draw by Hull City at Old Trafford last time out.
That stalemate was the Red Devils’ third in a row in the Premier League and dealt a blow to their top-four hopes.
And Mourinho admits that Manchester United must improve their form in front of goal if they want to finish in the top four this season.
Mourinho said: “I hope the goalkeepers make mistakes against us like they do against other teams. I see many goalkeepers make huge mistakes the week before and against us they all look absolutely fabulous.
“I hope that the relation with the post becomes better. I also hope that in front of goal we are more objective. We go really to smash the ball in the net because we also miss goals one metre from the goalline – and not once or twice.
“So I agree with and understand this question. There are teams that are very defensive and they score with their first shot; with us it’s the opposite.
“We always start the game to play and to try to score and win. We don’t lose a match in the Premier League since around 20 October.
“It’s a lot; it’s three months or so, but we should score more goals and win more matches.”
