They arent just paying those fees cos they can, they are paying them to get those players to A. leave their settled clubs B. Move to an almost unknown league and become a face of that league and C. To convince the selling club to actually let their superstars go, weve probably received bids for Pogba already.
I'm aware of those factors, but then again I read of a Conference (or less) player here who has gotten himself a contract in China for about £20k a week. That is basically a lottery win. It basically means that if you are, I dunno, some goalkeeper at Macclesfield - you could be earning up to 1000 x more and maybe even be one of the better keepers in the Chinese League.
