Manchester City's form this season cannot be compared with Liverpool's poor form. Liverpool have some work to do to get them back to winning again. Manchester city are looking much more favorites to win the league again this season, Arsenal have showed they can be competitive but I doubt their squad is good enough to carry them till the end of the season.
Liverpool's inconsistency at the start of this season has made them doubtful about being able to continue to compete in the top flight. I think this season again belongs to Manchester City because they have a fairly complete squad so it's very difficult to beat. Arsenal are not strong enough to last until the end of the season, control the champions league zone until the end of the season I think something great achievement for them. Manchester United and Tottenham will be tight competitors and will be a bully to Manchester City.
Luckily Manchester City managed to get Erling Haaland because his presence can make progress for Manchester City and it has been seen that his contribution there is very much because so far Erling Haaland has scored 12 goals in eight matches that have taken place, so this is really a great achievement for the club. Erling Haaland early in his career at Manchester City.
The major priority for Man City this season is winning UCL trophy which eluded them last season due to non availability of a competent striker, Guordiola resorted to play false nine in crucial matches, I believed the signing of Erling Haaland will address that problem now, as for the league No team can match the club presently, it's Man City first while others follows though Arsenal is showing some remarkable performance and improvement this season, however I don't think they can be consistent in winning their matches partly due to injury to some of their key players and lack of depth in their squad, While Tottenham had improved too, Chelsea and Liverpool are still struggling with form.
I don't think that Arsenal will be able to hold on to their performance until the end of the season because they don't have that much squad depth. Manchester City really lacked a lethal striker for the last few seasons after Sergio Aguero left. But now as they have bought Erling Haaland, they will really try to push for the Champions League title which they have been wanting to win for the first seasons but were unable to do so.
So far Haaland has shown what he is capable of as he scored 10 goals in only 6 matches. So far Chelsea and Liverpool have been playing their game this season so Manchester City might have a really good opportunity to grab this and be the best team in England and possibly Europe.
I think that this is to early to come to such conclusions although I agree with you,Manchester City needed a perfect striker from quite some years now,they were lacking in the Champions League because of that,especially last year where they got eliminated.In the Premier League though they are doing great again and having a squad depth means it can only increase your chances to become Champions especially when your contenders like Liverpool and Chelsea are screwing up game after game.
