Manchester United interim boss Ralf Rangnick has warned that his team shouldn't have to rely on the heroics of Cristiano Ronaldo.
The Portuguese star hit a hat-trick as United beat Norwich 3-2 at Old Trafford, with the Red Devils surviving a scare as the visitors equalised after being 2-0 down.
Despite United moving up to fifth place with the win, Rangnick was far from satisfied after the game and criticised the team's build-up play and defending.
Speaking to Match of the Day, when asked about Ronaldo's contribution Rangnick said: 'We should not only rely on him. We played well at times but we sometimes slowed the game down and didn't make use of overlap situations on the wing. Defensively I was not happy at all.
'The results elsewhere were good. But it doesn't make sense to look to other results. We need to raise our game.'
Rangnick bemoaned United's lack of aggressiveness following Ronaldo's second goal and added that his team lost their structure.
He said: 'After we scored our second goal we should have made life easier for ourselves but we didn't.
'We lost our structure and weren't aggressive enough.'
Rangnick did, however, praised goalkeeper David de Gea for making some important stops.
He said: 'It's about being clever and smart. All of a sudden it was 2-2 and David de Gea kept us in the game. But we definitely have to raise our play.'
United are three points adrift of Tottenham, who currently occupy fourth place. There are two crucial games on the horizon for United as they face Liverpool and Arsenal away.
Rangnick was eager to point out that United must improve if they are to take points from those fixtures.
He said: "If we want to get points out of those games we have to raise our level and play our best."
