Rosell being corrupt isn't new, he was already accused of funneling money from Brazil's friendlies into a US bank account in his name (yet that has apparently been brushed under the carpet because I haven't heard about it in months). And Neymar transfer was shady from day one, saw that coming from miles away.
Laporta should come back, he might have done some questionable stuff too but he was awesome. Rosell is just a dumb shit.
