A very interesting mercato we are going to have and hopefully better than
previous ones. I would buy Kolarov (LB), Kjaer (CB), and pay the 10-12 million for Caceres. Some may say it's too much money on defense, but we need to since our defense is just horrible conceding over 50 goals this season. I would add Hazard, and a forward. I would love to get Suarez. I still believe that Diego would do a better job right infront as a trequartista near to the box than a play maker. He would be more dangerous. He is more of a del piero than a Zidane type of a player (P.S I know he isn't either, I am just saying the style

)
The formation would be the 4-4-2, a formation I usually prefer because it keeps the players close to each other and short passes should be easier in that situation.
Buffon
Caceres Kjaer Chiellini Kolarov
Marchisio Melo
Hazard Giovinco
Diego
Suarez
Only 5 new players ( Hazard ~20 millions, Suarez ~ 20 millions, Caceres 12 millions, Kolaraov and Kjaer both around 15 millions each), so the total around 80-85 million. The budget for the next mercato is reported to be 80 millions before the sales, after sales this number could go down to ~50 millions which very reasonable.
