In terms of future egg on face, well I'm currently predicting that c£30m for Bony, plus wages etc, will turn out to be a complete waste of money by City in this FPP era. So long as the money is made available for Swansea to reinvest, I can only see one winner out of this deal in the medium to long term.
Oh, if we're talking future egg on face, I will scoff at those who say we are going to beat Real Madrid next season.
