I wouldnt switch Zlatan for Gila-Cassano either.
If Zlatan doesnt score, he passes to someone who will.
Improve his finishing and he will be the perfect forward. Tall, Fast, Strong, Technical, Tough to take the ball from.
And besides id rather have two forwards scoring about the same amount of goals then one scoring 22 and the other scoring 7.
Forget about Cassano or Gila, we have all the attackers we need, and then sum, We need to start looking for a replacement for Neddy, i think he only got two more years in him.
