Chelsea's inconsistency this season has indeed made us unable to fully trust them. Currently Graham Potter's reputation seems to have been saved thanks to the victory in the Champions League. but I also doubt whether the improvement that has occurred in the Chelsea team can continue in the Premier League. Maybe we can assess it further in the game Chelsea will face this week against Leicester. if Chelsea can win this game then I will be sure that Chelsea have indeed returned to their better form.
Of course, no matter what players they have, if the coach does not have good competence, it will not produce a good team. It happened to Chelsea, I think Potter is not the right coach. I think if at the end of the season there is no change he should go. Chelsea should have no problem choosing a quality coach. There is still a large selection of coaches who do not have a job at the moment. For the next game, Leicester is not a big deal for Chelsea. They should be able to win and get three points.
