Ralf Rangnick praised Manchester United for the aggression they showed to beat Aston Villa in the FA Cup on Monday night, but revealed his frustration at their tame pressing game.
United booked their place in the fourth round of the cup thanks to Scott McTominay's glanced header, but it was far from convincing as Villa staged an impressive fightback.
Ollie Watkins cannoned an effort off the bar and Danny Ings saw a goal controversially ruled out as United dug deep to thwart Steven Gerrard's side and hold onto a narrow win.
After the match, Rangnick hailed the aggression shown by his players but once again demanded more from them in regards to their pressing approach.
"I saw more aggression but I didn't necessarily see that much more pressing," the interim manager told MUTV. "In order to see those pressing moments, you have to get into those pressing moments.
"As I said, it's difficult against Villa. But what I saw was a team that desperately wanted to win and in the end, that's why we won the game."
David de Gea produced some more fine saves to ensure United held onto the win and he received special praise at full-time for another huge contribution to the team.
He added: "We have to develop the team into a clean sheet team... that was another one today but still David de Gea was outstanding.
"I'd have wanted him to have less saves in total, I think we had four-five shots on our goal, but again we can still improve even in that area."
