The one weakness with a coach like Conte or Del Neri, is they think about a formation and choose the players. Its better to get the best players and let the formation work around those players. Tactical diversity is also important....if later we like to switch to a 4-3-3 we need another quality mid and Pazienza is not what I call a great starter.....we only have Vidal, Pirlo and Marchisio....any one of them not available and we lose lots of quality in a 433.
Krasic can't defend...he is better at attacking on the right.....he would play better in a 4-3-3. Vucinic would be best in a 4-3-3, Pirlo would be best in a 4-3-3 etc.
Vidal-Pirlo-Mascherano would be heaven and we could have Marchisio and Pazienza on the bench. That wouldn't be bad at all.
In fact......if you play with that kind of team, you could still opt for a player like Bastos who is equally adapt at playing as a winger or left back. If Mascherano costs even EU20m and Bastos 15m, Alex 10m we would truly have a starting X1 that is scudetto material. Our total gross spend would be just over EU80m (excluding the buy-outs of the loaned players from last season). Sissoko and Melo (if you include his buy-out clause) raise 20m....which brings the net to 60m....and I am sure you can get at least 10m from selling Martinez, Amauri, Iaquinta and Manninger.
Plus the team would have many tactical options with Mascherano.
Starting 11:
-----------------Buffon----------------
Lichsteiner----Alex----Chiellini----Bastos (I know not going to happen but I would have done it)
------Vidal----Pirlo-----Mascherano----
---Krasic------Matri/Quags-----Vucinic--
And if you want to play a 442:
---------------Buffon--------------------
Lichsteiner-----Alex----Chiellini----Ziegler
Krasic------Vidal----Masch/Pirlo----Bastos
-------Matri/Quags-----Vucinic----------
or hell even a 4-2-3-1
-------------------Buffon---------------------
Lichsteiner----Alex----Chiellini-----Bastos/Ziegler
--------------Pirlo----Mascherano--------------
---------Krasic-----Vidal-----Vucinic/Bastos----
------------------Matri/Quags------------------
By the way, even if Bastos is not possible... Vargas also has experience as a left back and could give us more tactical options as well.
