People seem to forget that Potter was at Östersund first and seem to think he first appeared at Brighton. But his Östersund record is amazing: he brought a fourth league team to the first league, won the Swedish FA Cup, and subsequently reached the Europa League group stages and then made it into the knockout stages. (With good football, I might add.)
Sweden is far away and unknown, and so his next step was Swansea; but if he had done something similar in England (like Wilder but better), he would have most likely been hired by an established (sub)top team.
To be clear, I don't know if Potter is United material (not meant negatively, I just don't know), but at least it'd be good if his full record were considered in these discussions, not just his time at Brighton.
