Bastos, Vidal, Rossi & an experienced CB will easily compete for top 3, maybe even 2nd spot since merda is selling Sneijder to Man U. Our main weakness from last season has been fixed with Lichtsteiner and Ziegler (providing Ziegler plays well). Bastos would be a great addition because of his ability to at LB. If so, Quag or Rossi could be probably be shifted out to LF/LW.
Although, I'm not sure that Rossi & Vidal are even necessary. Melo could play the midfield destroyer role and Matri & Quagliarella (injury free) can easily score enough goals. With the money saved from not buying Rossi & Vidal (€40m+) we could buy a LW backup, RB backup, buy a better CB to partner with Chiellini and a LB (Cissokho).
