Actually is about Allegri.Cuadrado can defend better than Lich and not to mention about the attack.But as I said it's to attacking formation for Allegri if he deploys Cuadrado as a fullback.
About D.Costa signing,confirmed by who?And to be honest I don't watched him while he was playing for Bayern that he plays on the right side.Maybe I am wrong but I always see him playing at the left side.....
D.Costa is better on the left,maybe he exclusively play on the left.I am a big fan of him but he costs at least 40 mil.Bernadeschi plays on another position and Keita is good but yet has to prove himself in a bigger club than Lazio.
