It's too early to write off Man City although they are far from their best but they can still come back. The most consistent team is always the victor in the end. Liverpool, Arsenal and Chelsea have started well but I'm more skeptical about Chelsea consistency which I know can be really disappointing looking at our last season performance where we almost miss our top four spot.
In my opinion, Manchester City strength in the competition for the trophy cannot be underestimated. After all, Pep Guardiola is a very experienced manager, and he has enough squad depth to get Manchester City back on the right track. It's still early in the season, and no one knows what will happen in the next 35 matches, Manchester City might be able to turn things around.
Of course, Liverpool, Chelsea, and Arsenal, who are currently playing more consistently, look more convincing to win the race. However, it's not certain that they will be able to maintain that impressive performance in the future. On paper, their chances are better than Manchester City right now, but it's still too early to say that Pep Guardiola team will fail to win a trophy this season.
