Also, Arsenal did not only sign Kai Havertz in this transfer window because in fact, Arsenal also managed to sign Declan Rice as their highest transfer at this moment. Thus, then of course Arteta is very earnest to make the team's performance even better next season, so you should not underestimate Arsenal. Although indeed, Manchester City still looks strong but that does not mean Manchester City will easily be able to win the Premier League trophy again. Thus, the competition in the top zone will certainly become more interesting, because the clubs in the Premier League have very good abilities in a very competitive competition and it is very different from other leagues.
Win, you are right that so far only Arsenal has been able to provide a tough fight in Man City game. Therefore it makes sense that it is difficult to underestimate Arsenal seriousness in the next season. In terms of his involvement in the transfer market, Arteta is quite ambitious and does not want to waste the opportunity to strengthen his squad. The support of all parties involved seemed to fully entrust the future of Arsenal to Arteta. So that he can freely form the ideal troop up to this point. Kai Havertz and Declan should be watched out for when dealing with the right people, they can be a serious threat to the opponent's defense. In addition, the combination of Martinelli, Odegard, and Gabriel Jesus is certainly quite solid in building attacks.
It is going to be hard for Manchester City in the next season for sure. Because I don't think the clubs which did not perform well in the last season will actually stay on the sideline this season as well. I believe there will be a bigger competition in the English Premier League this season. Arsenal is obviously doing what they can to make the team stronger.
It is also true that Arsenal has a very solid squad right now. Of course, it is better than the average mid-table team in the English Premier League. I don't know if I can actually say that the attack of Arsenal is one of the best in the world. But it can certainly get the job done. I agree that the other teams are going to be fearful of Arsenal in the upcoming season but Arsenal will have to perform consistently.
