But he's right, Candreva won't solve any of our problems. He's not the sort of player we needed.
I think we actually do need him. If he's brought here to be Camo's replacement then this move would make lots of sence.
I think Ferrara reallized few weeks into this season that the 4-3-1-2 system would never work with Diego in our team. He probably figured out just like most of the guys here that the 4-2-3-1 formation is the right way to go but he simply didn't have depth for that system.
He tried to survive with our team till january when the market re-opens again (but the results were horrible and that didn't help him much). We brought Candreva plus got Iago as a back up for that system.
A combination of horrible mistakes from the management last summer in the market, constant injuries to our players plus Ferrara's inexperience are what causing us all these bad results IMO.
