Indeed, Haaland scored a hat-trick in the Norway vs Kazakhstan match with a full 5-0 victory. At club and national team, he has always been a giant, and he still has it.
Haaland did in the national team what City lacked in the last matches, when they scored one goal per match. This only says that Haaland is in good shape and there is hope that he will continue to score for City.
Indeed, when his club, Man City was quite down, and so was his performance at City, finally Haaland was able to show his skills again in his national team. And even for now, Haaland is the top scorer with 7 goals, above Sesko and Ronaldo who each have 5 goals.
By the way, in this match, Sørloth also scored, Norway now have very good forwards up front, and this was an important victory, because Austria lost points in the last match with Slovenia and now Norway returns to League A.
as you said, Norway currently has a strong front line. Sorloth is the same, with 3 goals and 2 assists. The Norwegian national team's goal productivity has also been quite high so far, 15 goals, but their defense still needs to be improved, conceding 7 goals. But what is certain is that Norway managed to become the top standing of the group and promoted the next qualification.
