Its a straight swap, no money to get Sanchez. However, 10-15M might be needed to lubricate the wheels of business agents fees and paying arsenal Mkhi's sign on bonus or such like things. As he has no sign on bonus, supposedly, he can demand higher wages, which is the same thing really only over a long period of time. His contract renewal (if) would see him paid much less per week. Remember Zlatan was on 350Kpw as we got him on a free. Add into that we are saving/offsetting 170Kpw Mkhi's contract. We are selling a player too. So the deal balances the books somewhat. Basically, we pay 15M ish and the 170Kpw wages more than we already were paying Mkhi for a top Player. To one of the footballs top 5 clubs it's a pittance for a player of Sanchez quality. Even if we throw 30M sign on bonus to Sanchez it's still a great deal. Which is why all them cryin cnuts are bitching and moaning making up silly numbers adding on the price, with taxis and chartered planes and what not. To continue the narrative/agenda that United are clueless in the market. Which you can see they are not. They wiped Citys eye with this deal its Alves all over again! Don't forget that City are off crying in the corner over this! They even invented Chelsea, they were that salty!
