This squad now looks really unbalanced for a Glasner 3421. Savona is definitely no wingback, so, unless they can use Cuibaino, Richards or Moreira (or even Backwa), we only have three possible wingbacks and how many games is Aina going to miss if he needs to cover that much ground? We have 7 or 8 competing for the two behind the main striker and MGW is taking one of those two (unless the extra security at the back means he can play deeper).
