All hard to remember, unless one's got a balance sheet in front of them...
Pepe and Qtube are surely done, I did think that Matri had something left, but it would be nice if he didn't. Not sure about Licht, or Vidal - were those done as a one time payment? How many more payments do we owe Milan for the best midfielder in Italy
Anyway, not to get too bogged down without details, but the more general point was that there are likely some expenses that aren't immediately apparent. If there aren't, that's amazing (and surprising to me).
I expect that the Udinese deal, as well as the Giovinco transaction, might involve only 1 or 2 payments max, so the teams have funds to replace key players. Anyway, all speculation. Gotta love mercato season, especially before the market officially opens.
