I think tolmie intimated that it might be a problem but my sense was that it was more on the basis of having another bidder able to pay over the odds. Maybe something about being closer to family for the player.
I'm with whomever said earlier that anyone that would rather play in Ligue Un than here isn't really of the mentality that you'd want anyway.
Also, at the wage level KDB could get here PSG would have to pay a giant distance past what we would to compensate for the daft French tax rate. They're closer to the knife on (modified) FFP than we are to begin with. I think for that reason alone there's probably not much to this chatter.
BTW - fair dos to that Anonymous fellow. Probably still full of shit, but certainly steadfast in sticking to his guns here today when Bayern's little farm club seemed to be organising a torchlight parade to commemorate KDB's apparent change of heart.
