If he in any way contributes to Parma winning points tonight, then both our directors and Giovinco should be hanged.
It's quite easy: "Seba, we plan to take you back. You proved Juve wrong. We're now fighting for the scudetto and the Parma match is a must win for Juve. You know that, right?"
If this wasn't said to Giovinco or if he was told but he didn't understand/won't do it, then neither our directors deserve to run Juve nor does Seba deserve to come back.
