At least Chelsea now is not too bad because they managed to be in the top 4 of the Premier league even though there are still many matches.
Maresca can be said to bring change, and at the beginning of the season maybe Maresca will change the plan for the better so just wait for his action.
If compared to last season's results, indeed this season, Chelsea is quite improving and that's quite good, at least for the time being they are in 4th position, yes although it is still quite risky to possibly drop back down, because the competition for the number of points is very tight with Man City, Newcastle, and also Brighton. So, Maresca must be able to make his team stronger and consistent to win, otherwise they could drop back to the top 6. This will greatly affect their table results at the end of the season. and the next match will be a very difficult match against Tottenham. in the last 5 matches, Chelsea's results have not been good, so if this continues, then they will be forced to drop down again.
