They've subtly counted the Sane money twice, once when the deal went through and now counting a big chunk of it again because Bayern are paying in installments. It's a load of bollocks and just a weak PR move to desperately try and make it seem less like they're just buying success.
It makes sense for them to try really, owning the club is just a PR/sportwashing move for Abu Dhabi, so it's in their interest to try and make it seem like they play by the same rules as everyone else.
