Yes, it's too soon to draw conclusions because the Graham Potter era has just begun. He did fail to make a big debut, which Chelsea could only draw against Red Bull Salzburg but that doesn't mean Chelsea will continue to sink. As a new coach, it's obvious that he needs time to adapt so he can explore the potential that Chelsea has and the possibility to find the best composition of the squad. I think Graham Potter definitely has his own shopping list and if he is given full support in the upcoming transfer window, it was certain that he would make the best of the opportunity.
It could be that his debut with Chelsea provided an opportunity because the differences between the management of Chelsea and Brighton were very different. especially in its players which Chelsea may have a distinct advantage if managed properly. In addition, the Chelsea manager should not be in a hurry to take the decision to sack him as he did with Tuchel. so giving Graham Potter more chances will prove he can save Chelsea. Many of the clubs Chelsea is currently facing have grown stronger, in both the Premier League and Champions League so Graham Potter must make the most of this
Potter has indeed succeeded in bringing Brighton to a different level. But he had never coached a big team before. Therefore, not a few doubt its capacity. The appointment of Potter was a gamble, but Chelsea management believed and kept giving him time. But in my opinion, Chelsea will suffer from setbacks for a long time and they will also feel the lack of titles for many seasons.
