I don't think Iaquinta is a bad player, he's a good player, but simply he's not what we need. What can he possibly add to our squad? Nothing, our attack is very good, all he can do is add some depth, he definetly won't bring any extra quality.
Spending 8mil on a rotational player is not something I approve of, especially since we already have depth in our attack as it is. This attack of DP, Trez, Bojinov, Palla and Zalayeta could have served us perfectly well even in Serie A next season. But no, we decide to let a 21 year old Bojinov leave, even though we could have grabbed him for peanuts, and buy a 28 year old who quite frankly is not much better, if at all.
Iaquinta scores 15 goals per season for a mid-table club, mark my words if he comes to Juventus, next season he will be a rotational player with 18 games under his belt and 6 goals tops! It's different scoring for a big club, some think it's harder and some think it's easier. Personally I think it's much harder to score 20 goals for a star filled Juventus than a team like Udinese where everyone relies on one forward to the business. Just look at Dario Hubner few years ago for Piacenza, hell even Gilardino for Parma. Scoring in a competitive side where you have to fight for your place is a much harder task.
I simply don't see a need for him, not in my wildest dreams would I go for him. And if he's supposed to be a replacement for Trez, well, I'll just put a shot-gun to my mouth.
