Ibra for me, having 4 midgets in our attacking line is worrying, I believe Ibrahimovic will offer us something new, and could probably came use of all those crosses Alves showers into the box. He is a goal-scorer, I have no doubt that he will score goals. He's Inter's top goal-scorer and most of his goals are from moves he started. So I'm excited about the fact that he will be playing with Xavi/Iniesta/Messi ...
Plus the Italian league is probably one one of the toughest to score goals in due to their defensive fetish, so he scores 20+ there, he could definatley do it in La Liga.
