Exactly - all this "Why would he want to go there?" stuff is pure folly.
He would be at one of the biggest clubs in the country, and he would be managing in the Champions League right away. As an ambitious man, as he surely is, he'd absolutely jump at the chance. The "Chelsea is a basket case" is actually a reason TO go, not the opposite. If it all goes horribly wrong then his stint there is easily excused - "It was Chelsea and they are a complete mess" - his stock remains high and he'll not be short of job offers.
Are Chelsea really interested? Who knows.
Would Chelsea stump up enough to get Potter out of his Albion contract? Who knows.
Would Potter want to go if Chelsea want him and are happy to pay? Of course he bloody would.
Hmm. I would say that it cuts both ways. Regardless of the Chelsea internal set-up if he goes there and fails - then he's failed at Chelsea. In every other job that crops up post-Chelsea people will say "Yeah, he was great at Brighton, but he failed at Chelsea didn't he? Can't 'do' big clubs can he?" Saying "Ah, but the club was a basket case" will be met with a shrug. He still failed.
