Haaland has been the Premier League’s top scorer in his first two seasons with City, with 36 league goals as they won the Treble in 2022-23.
The Norwegian scored 27 times in the top flight last season as City won an unprecedented fourth straight league title – the return of a goal Guardiola said was “fine”.
Asked what he discussed with Haaland over the summer, Guardiola said: “I like when he runs a lot. I like when he presses like an animal. I like it. It helps to score a goal.
“When you are connected defensively, you are connected offensively.

“His body language – imagine a central defender has the ball and he makes a sprint with this body and legs moving. It’s scary.”
Guardiola said Haaland closing down opponents means “the people in the middle and back [can] support him. And we are more effective in our high pressing”.
The manager added: “This is not negotiable. If you don’t score a goal, it’s fine. But you need to do it.”
Haaland has made a positive start to the new season. The 24-year-old scored his 10th hat-trick for City during Saturday’s 4-1 win over Ipswich, giving him four goals from two games.
“He feels good,” said Guardiola. “Last season always he had problems in the hips, in the ankles, in the knee.
“This season of course he takes care of himself with the physios really well, but I had the feeling that he is sharper.
“After training sessions he stays longer to practise the crosses and controls. Last season it never happened because he was not perfect.
“With his body, he has to be perfect to perform at that level.
“That’s why you have an incredible organisation to help the players to be as comfortable to perform at their best.”
