After the swap with Atletico Madrid involving 30-year-old Fernando Torres and 27-year-old Alessio Cerci, AC Milan may need to sign a new center forward: according to La Gazzetta dello Sport, the rossoneri are thinking about 25-year-old Stefano Okaka, who doesn't seem intentioned to extend his deal with Sampdoria, currently expiring in June 2016. To obtain the Italy international, particularly admired by coach Filippo Inzaghi are ready to offer to the blucerchiati 30-year-old center forward Giampaolo Pazzini; this latter, whose deal with Milan will expire at the end of the current season, is also a target -according to the Corriere dello Sport- for Parma. The rossoneri are also seeking a new center back, and -as reported by Sportmediaset- they have overtaken Juventus in the hunt for Manchester City 21-year-old Matija Nastasic, who could arrive at "San Siro" on loan. Even for this reason, the Serie A defending champions -as reported by Tuttosport- are trying to speed-up the negotiation for FC Porto 29-year-old Rolando: the bianconeri's General Manager Giuseppe Marotta has found an agreement with the Portugal international, and must now deal with the Dragoes. The Piedmont's club is also seeking an attacking midfielder, and, according to La Gazzetta dello Sport, is seriously thinking about Palermo 25-year-old Franco Vazquez, who, during an interview accorded to goal, has been quite elusive about the possibility to extend his deal with the Sicilian club; moreover, according to The Sun, the bianconeri will have no longer to compete with Liverpool in the hunt for Bayern Munich 23-year-old Xherdan Shaqiri.
