Yeah, Wengers not been as successful relative to his early years but he's consistently made the champions league alongside teams considerably richer than Arsenal. Pep's his natural successor though, but I don't think they'd have the money for the kinds of transfer budgets he'd expect. And for Pep, it'd represent a definite step down after Barcelona and Bayern. (ditto Liverpool - in terms of a step down)
If (massive if) he comes to the Prem, it'll be to either Chelsea, MU or MC. MU can't compete financially with Chelsea or MC but he does seem to favour them, and he's more than rich enough not to be motivated purely by money.
But if he is, I'm sure Beckham would be happy to have him coach his Miami team. And Pep does enjoy the glamorous life.
Although he never quite gelled with the Bavarian club scene
