You can use the Camoranesi card on Estigbrira, not on both of them.
Anyway, I don't think anybody rates Giaccherini after seeing him miss that goal, cuz thats stupid. I was actually really excited about him the first game against Milan when they played well and I remember calling him Giovinco's bro. But still, I feel like we're not taking the proper steps with him. He's a slight improvement.
