Chelsea has to work on their defence line and how to coordinate them, assuming they played against Arsenal or Liverpool and they scored an early goal as Tottenham, I don't think they can make a way out due to their current performance. I'm happy for their victory because they are able to make a different against arsenal that were competing with them. At least they are two points away from arsenal which they can maintain.
The silly mistakes in the match against Tottenham, especially for the 2 goals scored in the first 11 minutes, prove that Chelsea still have to prepare and improve to be better. In addition, it is actually not only the defense that needs attention but also teamwork and individual players which in my opinion at this time Chelsea players there are only a few who shine enough and the other players are helped by it.
As in the match against Tottenham I only saw impressive performances from Palmer and Sancho which were very clear, the rest I did not find anything special from the other Chelsea players so this must be noticed that in the end there must be some changes that must be made even though Chelsea are currently quite different when compared to last season but on the other hand they also still need to improve the quality of their team to be more worthy of being in the top standings this season.
I think Chelsea are on their way to peak form, and to be honest they are much better than last season. Enzo Maresca certainly knows his team potential well, as well as the weaknesses that he needs to fix in the upcoming matches. As time goes by, Chelsea seem to be able to compete with Liverpool at the top of the standings. Cole Palmer and Jadon Sancho are starting to be the main focus of Chelsea revival, and both players were important pillars when Chelsea beat Tottenham in the match week 15.
Chelsea current player composition is very balanced, although some of them look more prominent thanks to their individual abilities. In the future, with the chemistry that is increasingly formed, Enzo Maresca will have a more solid team, so that they are able to achieve victory with a clean sheet record. Most likely Enzo Maresca will be able to meet expectations, even though at first many people doubted his ability.
