I think there's a fundamental difference between the two problem makers.
Cassano - a spoiled cry-baby. The kind of man when things don't go his way, sits on the floor and cries without the will to do anything about it.
Balotelli - I see him more of a egocentric, like C. Ronaldo or Ibra, but with a bigger knack for tantrum. The kind of man that's aware of his abilities and strives for people to recognize him. That drives him forward.
Surely, both are risky with their personalities, but if you ask me, Balotelli's mental toughness is miles ahead of Cassano.
cant compare them im just saying id take balo, based on the fact he is a lot younger and already real good and will improve,we will see the two in the future
What Cassano can do with the ball, Balotelli can only dream of. Balotelli cannot pass the ball as well as Cassano can, he isn't as creative as Antonio and he doesn't have the exquisite first touch and dribbling ability Cassano has.
