Lavezzi is too old for us. In the next two summers we should be replacing Buffon, Pirlo, Tevez, Barzagli, Padoin, Evra, Pepe, vidal and/or Pogba, Licht. We'll be left with Marchisio, Chiellini, Llorente as our seniors while Asa, Caceres, giovinco Ogbonna, Bonnuci and Pereyra will be peaking and Koman will be developing. In other words, all our top players will either retire (Pirlo and Buffon), leave (vidal and pogs), or become too old.
Marchisio, Chiellini, Llorente and Asamoah will be our only reliable starters and three of those will be old.
Lavezzi would be another player that would need replacing. I dont mind old players on the cheap but I'd never spend much on a player who will be too old in a matter of two years. Lavezzi is better than Iturbe and Lamela at the moment but they are the better investment for the future.
