I don't care the kind of form West Ham is in this is a match Arsenal should have won. They messed up by losing this match to West Ham. They were at home and they had the advantage. Is West in a better form than Arsenal?
This is just what Arsenal do, they always bottle their opportunities. They were supposed to win the league the year Leicester won it, they were supposed to win the league last season but they messed up and allowed Man City win it, now they've lost and giving either Liverpool or Manchester City a chance to win the league again.
Now Manchester City has an outstanding match, if they win that match they'll be second and top Arsenal with goals.
There have been clear signs of progress for Arsenal this season, but the 2-0 loss to West Ham raised familiar questions. Not only Man City but also Liverpool are ready to compete for the Premier League championship this season. Man City is only 3 points behind and has played 1 match less. Arsenal appeared to need more composure of a championship team. The organization of the defense had apparent problems in the first goal. More significantly, before conceding, Arsenal wasted a series of opportunities. The addition of personnel is necessary for Arsenal to avoid going into the "trail" of last season when allowing Manchester City to overturn the odds and lose the Premier League championship. Mikel Arteta needs to have urgent solutions. If there are no additions soon, going down the same path as last season is entirely possible. They need a central striker. Arsenal must win another derby with Fulham to consolidate their position.
In fact, I have already said what I will say in another thread that actually those who are at the top of points table or in the top 3 have performances that are not worthy or I mean Arsenal, Liverpool and Aston Villa are not yet strong enough to be leaders of the Premier League and Look at how Aston villa was beaten by Manchester United and Asenal was beaten West Ham.
From the conclusion above, we can estimate that to be able to maintain a position in first place in points table, you must have very high consistency.
Meanwhile, we have to know that Manchester City will get back its mainstay player after going through a period of injury. Haaland is likely to appear again with Manchester City in the next match.
The most important thing for me is that several clubs above Manchester City will only be temporary if MC improves its performance again and will definitely move back to these 3 clubs and dominate the Premier League again.
