Interim Manchester United boss Ralf Rangnick wants his new side to up their intensity - and then some.
The German reckons there are several areas where the Red Devils can improve despite their hard-fought 1-0 win over Norwich on Saturday.
Cristiano Ronaldo's 75th-minute penalty earned United all three points at Carrow Road.
They are now unbeaten in six games since Ole Gunnar Solskjaer was sacked.
It saw United move level on points with West Ham in fourth before the Hammers' trip to Burnley on Sunday.
Goalkeeper David De Gea was kept busy for the visitors and their display lacked the pace of last weekend's win over Crystal Palace.
Aggressive
"Norwich played in a very proactive and aggressive way, so it was a question of how do we deal with this kind of football," the German said.
"I wish we had more intensity up front, more physically and more willingness to win the one-v-one duels.
"We could have done better in some parts. In some parts it was good, like the whole defensive line, the six including De Gea were good.
"Offensively we also had some nice moves but didn't find the best solutions in the first half and second half after we scored goal, it is a question of intensity and we conceded too many free-kicks and corners.
"It was a game where something could never not happen and we need to change this."

It was a second clean sheet on the spin for De Gea.
He made crucial saves to deny Teemu Pukki and Ozan Kabak late on.
Rangnick, who could lose Anthony Martial in the coming months, said: "It was a fantastic performance by David.
"He was probably man of the match, especially in the second half when he had two or three brilliant saves."
United centre-back Victor Lindelof being forced off with what appeared to be breathing problems with about 15 minutes left.
Collision
But the manager explained: "He can't even remember himself how it happened.
"I think he had a collision with another player and had problems to breathe.
"For more than 10 mins his heart rate was higher than normal and he was a little shocked by this, so we had to replace him.
"The doctor has checked him after the match and it seems everything is okay now, but we still have to see how he is doing tomorrow.
"Hopefully he will fit for the Brentford game."
