If we compare formally, Arsenal scored a solid 84 points, which, although less than Liverpool's phenomenal (for second place) figures of 90 ++ points, but more than, for example, the number of points that Leicester scored in their championship season. Therefore, I also think that many teams showed a good level in the Premier League, but the fact is that City are in a different league and now it is almost impossible to compete with them.
Now let's imagine if Haaland gets injured who has contributed 36 goals what will happen to Manchester City still reliable? so this is where Manchester City's weakness problems like this can come at any time while Arsenal do not rely on one player they play their respective roles while on the field. I still have hope that Arsenal will be the strongest competitor for Manchester City so we won't see the dominance of just one team.
Next season is really going to be massive in the EPL because we have about five teams that will be fighting for that tittle,we have the likes of Mancity,Arsenal,Man u,Newcastle, Liverpool,and Brighton,and I can actually add Totthenham If Harry Kane does not go,but I doubt if he stays because it seems he is tired of staying at the club without winning any trophy,every player loves winning trophy to add to their names.
Nevertheless,I really see Arsenal to be very strong next season considering the players they added to the team,but talking about Manchester city in their reliance on Haaland,they have been coping without a main striker for seasons,they can make anybody top that forward line if he is out injured,and they will still be winning games, therefore he's not their only source of goal,they are only utilizing him because he makes the goal scoring effort more easier.
