I can not say Chelsea is a better team now but it is better than West Ham that has lost many matches this season. West Ham has not started well at all. Chelsea is opportune to play with small clubs in English Premier League after the club played with Manchester City but which was the only match that the club lost. Let us see what will happen because only 5 matches has just been played out of 38 matches that we are going to. I hope Chelsea will perform better.
When Chelsea are in good form, victory over West Ham can be achieved a little easier. We realize that the gap in squad depth has given Enzo Maresca a lot of advantages, West Ham who acted as the host could not do much this time. Statistically, West Ham looks more dominant, but Nicolas Jackson and his colleagues played more effectively. The additional 3 points made Chelsea successfully occupy 4th place in the standings, while West Ham had to be willing to occupy 14th place.
This is the 3rd victory for The Blues in a row, since the last time they lost to Servette in the Europa Conference League at the end of August. I agree with you in assessing Chelsea at this time, although they are starting to show signs of revival, we are still hesitant to say that they are now it's better than last season.
Enzo Maresca needs to prove this consistency in the next 3 matches, against Barrow (League Cup), Brighton (Premier League) and Gent (European Conference League), which in my opinion are 3 matches that are a little easy, it is a good momentum to gain fans trust.
