Suns you know I agree with you in regards to Giovinco, but in this matter you've lost the plot
1. Quag has proven once that he can have 7+ goals seasons.
2. He's known for is youtube goals, so this whole thing about him offering nothing is false. He's a great passer and scorer, His pass to Sissoko vs Milan is just one example. And his season two seasons ago was a great indication of what he his capable off, with the right determination he can put in a decent shift this season.
3. Btw he got more goals than Matri in less apps when you compare their best seasons for Juve thus far, and Quag was injured most this season and manaed 5? goals.
