Jovetić and Giovinco both had strong seasons but they still aren't looking like a clinical prima punta which we've not had since Trezeguet, so we're just going to disagree. None of our strikers can be considered very clinical on a European level, and Juventus will be found out in the Champions League if it's not addressed.
If anything, signing a player like Jovetić should be put off until next summer if needed, because of the depth we already have in Giovinco and Vučinić.
That's what I believe the team needs right now, and as a huge fan of Trezeguet I am constantly disappointed when I see the ball whipped into the penalty area or across the face of the goal and our strikers are nowhere to be seen. Or if they are around, they horribly miss the goal, which was a theme in many of the games last season.
Edit: I've been calling for Jojo for years as well, but presently Juve should be more desperate to find someone to fill Trezeguet's boots than to fill Del Piero's boots in my opinion.
