I also play Juventus and, assuming you are starting a new save from 13.3, there is a couple of things I'd recommend.
First, Pirlo - even at 34 - is just too good not to have in the team, especially in his preferred DLP Support role at the DM position. This could then leave you with Marchisio and Vidal in central midfield using either wing backs or wingers in support (I prefer wingers using Asamoah on the left - train him in crosses to start). Marchisio to be used as the attack minded CM and Vidal in a holding role.
Second, you will be getting Llorente on a free at the start of the 2nd season, who is possibly the best Target Man in the game. Until then, you have Bendter on loan for the first season, also a decent Target Man. Not the "best" individual striker in the side, but combined with either Vucinic, Matri or Giovinco, provides a lethal combination if you get the right supply to them, plus it will get you and the team used to playing with a TM while you wait for Llorente.
Take a look at JP's 352 Conte Tactics on this site to get more of an idea and maybe a good starting point for you
The only real problem will be how to replace Pirlo in a couple of seasons...
