Those who don't want Ibra think with their feelings on this one, they got hurt and feel betrayed; they would have loved having him stay. Get over it, we're not in a position to refuse a player like him.
Most of us, if we didn't have attachment to a club, would have done the same thing as him. Can't blame him for choosing what was the best option for him, plus he never had any bad words towards Juve.
