You cannot use only three matches to judge how the performance of a team will be like in the long run. Arsenal was able to win two out of three of their matches and in these three games, they played with two big clubs. Chelsea have only been playing with mediocre teams since the beginning of this season which makes me feel that we shouldn't use the matches played to determine the outcome of these clubs.
There is one thing with this point of saying or making it feel like it is too early to already be judging a team by their performance already in a few games but we fail to understand that it may be possible this is almost like the best this teams can actually do because tell me, if at the beginning of the season when it is presumed that they have their form intact since they have not been engaged so much, they are not doing well, is it at mid season when they must have played multiple league games both domestic and others and have some players injured or fatigued that they will den be able to do any better?
