June 15th is a very significant date for Milan's future- both for the ownership of the club as well as the transfer market. By this date the Rossoneri could have new leadership, and after that they will be able to start negotiations and sign new players. Franco Vazquez is on Galliani's wish list and there have been some recent contacts with his club Palermo.
Galliani and Palermo's president Zamparini are however waiting to see how the ownership situation is resolved by June 15th prior to meeting to try to complete the deal. Milan is targeting Vazquez, the pursuit will continue after June 15th.
