Potter has to be deemed a failure at Chelsea, even with caveats (he wasn't there very long; the squad assembling was incoherent and counterproductive to morale; Lampard is doing much worse) but a mediocre manager doesn't do what he did in Swedish football, (including good performances in Europe) playing actually progressive football, nor change Brighton's style around as much as he did from Hughton and build the basis for a Europa league team (which Brighton could well be next season under current manager).
They all have issues- Tuchel's not great at managing up, and can be a slightly abrasive or 'weird' personality at times, although a lot of players overall like him, but is a very good tactician; Potter's a really good training ground head coach, has high EQ and a good tactician overall, if not at Tuchel's level, who just got lost in the Chelsea tumult and didn't have the 'trophies' nor the technocratic attention to detail that wowed certain players with Tuchel. Potter, IMO, is probably quite close to a British Poch in his skillset, although he has more 'gimmicks' (from his Masters in management courses) and is a little bit less 'tough' in his manner when needs be: I think he'll do well with whatever upper mid-level PL league or maybe German team he can get a job with.
