Chelsea always starts a season with power performances, which is just that because of the lack of inconsistency; their performances are ending badly, but since a lot of people were saying that their performances have little improved, that means that they're ready to do well this season. Their last game was against Crystal Palace, which ended in a draw, but in the statistics their performance was very good since they were able to dominate the ball possession.
We can wait and see what their outcome against West Ham will be; after that match, we can determine whether they will do well this season since their performance in their last game shows that they’ve been slowly improving. We will see how the whole season goes for them because it’s not by starting the season with a great performance how the season will end is the matters.
Chelsea against crystal Palace was really something else as many people thought they will win and picked Chelsea straight win in various tickets only for it not to come through. Crystal palace will be a team to watch out for in the coming matches, I hope the sale of Eze will not really affect them in their upcoming matches. We wait till see what Chelsea will play against West Ham as you have said.
