I bet that Haaland not only will continue to score goals like that, but he will also score a lot more. The main reason is that everyone is tightly marking Haaland now, which results with him not being able to score that easily, but if he can't score easily, then how could he score more?
Yes, even when facing Madrid and Inter Milan in the semifinals and final of the UCL last season, it was even difficult for Haaland to score a goal. He was guarded closely by the players at the back, but it was a big mistake for Madrid and Inter Milan to think that Haaland was a big threat to them, even though the other players in manchester city is far more dangerous and can score goals that's why there are always surprises from manchester city.
Guardiola really knows where the players are placed so that when Haaland really couldn't score a goal because he was guarded very tightly, of course other players could freely score goals against their opponents, that's what Manchester City did when they beat Madrid and Inter Milan in the UCL semifinals and final last season. thus making Manchester City get the treble winner.
