Did you watch the Euros? Abate is actually capable of crossing the ball well. It's just that for most of this season his target for crossing has been Ibra who quite frankly would prefer the ball played into feet, anything above chest height is waisted on Ibra. Cassano can both cross and create as evidenced by his turn to get away from the defender and playing a beautiful cross for Balotelli against the germans. To say we lack crossing ability is unfair when what we haven't had is the penalty box presence of a CF this season.
Im all for Dzeko coming, especially if that means Ibra leaving, as much as I appreciate the Scudetto he helped win, his presence really does limit our tactical options, the ball has to go through him and he has to be the centre of attention or he throws a fucking hissy fit. We've had better players than him at Milan and none of them had as poor an attitude as Ibra, you try a pass that doesnt work out in nearly every other team and the target will applaud the intent as they know it doesn't always work out, with Ibra you get a bollocking because you didnt get it right, that sort of behaviour is detrimental to team morale and can cause players to not make a pass like that in future if thats the response they get when it goes wrong.
Dzeko is one of us, and had he not had the footballing ability that we all lack he may now be on here or another Milan forum posting about the team he loves.
