I'm afraid i have to disagree with this opinion.
Giovinco on the wing, was more of the same stuff. Basically he tries to take on defenders, and NEVER gets past them, allways looses the ball. The only good thing he did from the flank, was that one game where he was switched to the right, where he cut back, and send early crosses with his left foot.
HOWEVER, if we were to pounce on this and make him set his game to this, soon defenders would figure it out, forcing him to take them on instead, losing the ball.
Giovinco was best when lots of space was to be found, and springing on lose balls. He however has shown an ridiculous lack of composure and mostly ballooned these chances out of the stadium. At his age, he could improve here, but nothing groundbreaking.
I'm all for using him as a supstitute for counterattacking play.
But one has to wonder, if we aquire Higuain who has a great burst acceleration and good top speed, and possibly Jovetic on a trolldeal, if Giovinco still has this use in the team ?
With Llorente-Higuain starting, we'd have Jovetic who is better at allmost anything compared to giovinco to possibly come on and do the exact same thing as giovinco, but has the added value he can also start regular games aswel. And then there is the Vucinic relation.
If we can get Higuain and Jovetic, there is no room in this juventus for Giovinco.
