No, the issue is the business style of FCB. They often pay a lot for meh players who where never suited for a club like this just like Kounde.
For instance, Q$G and Madrid are known for paying big bucks for top players/prospects, that's why their players usually have a high resale value.
Before putting Kounde in the meh area let's see someone better we can realistically sign. I haven't seen anyone better in a clear and decisive way except Hakimi over the last 2-3 years. I am all for signing some unproven talent and maybe develop him, but we ain't seeing that either. All I see is let's sell Kounde and we'll figure out what to do later. This doesn't fly.
Bayern have some pretty crap fullbacks themselves. Laimer for example has been a disaster vs PSG. Been a disaster at this World Cup also. Before shitting on your own players at least look at the alternatives.
The offer on display is pretty shite. Hell, Pedro Porro is probably one of the best these days.
