Nketiah scored 5 goals in 27 games last year. He wasn't a very productive forward. Crystal didn't start the league very well this year either. Arsenal actually lacks a forward like Haaland. The last time they didn't have a forward was probably during the Thierry Henry era. They must be an unlucky team because they've been feeling this lack for a long time. I think they need a forward like Haaland. Haaland scored 100 goals in 105 games for City. A statistic that could make them champions on its own.
Every player in the front line must have the instinct to score more goals because their job is to be able to finish well when there is a pass from their own team mates. While Arsenal's front line players are not like that although I also don't think they are bad because for this season Arsenal is still quite good in the domestic league and also in the Champions League. So they only need a few new adjustments to be able to increase their strength in the front line even though they don't have players like Haaland who always get more support from their teammates.
If we look deeper into comparing Arsenal and Man City, it's not actually a problem that Arsenal must have a striker like Haaland.
Now let's look at it logically and take examples from other league teams like Bayern Munich and Leverkusen.
Last season we all know that Munich had Kane with his scoring machine achievements and made a big contribution to the team. We even have predictions that Munich will be stronger last season. But the facts say that Leverkusen won the bundesliga title. While Leverkusen does not have a player like Kane.
Well, the conclusion is that Arsenal does not need a player like Haaland because Arsenal performance is actually very good. But what Arsenal needs is strong consistency.
If we look at Arsenal at the beginning of the season, they always give extraordinary performances both domestically and in the UCL. But at the end of the season they lose their energy and their performances are inconsistent.
