Buffon, Cacaeres, Kjaer, Chiellini, Criscito, Sissoko, Melo, Giovinco, Diego, Sanchez, Dzeko.
Only 4 players. Not bad. Only 1 not from Serie A, besides Caceres which kinda doesn't count.
Use Gio consistently for a season to raise his value then once we get CL football we can replalce one or both of Melo or Sissoko, sell Criscito for the next step up LB, and trade Gio for Di Maria or Hazard perhaps.
Baby steps, easy buys this sunner plus one big buy to get us top 4, then next summer go big once we secure CL and move into our new stadium.
There is no reason why a good manager couldn't make Melo/Sissoko work this year. If things work out, keep them and continue to splurge on D.
