I see you've been easily confused, so i'll simplify this
This scenario is about Cavani coming to Juve IF he was involved in a swap deal with Pogba. This is NOT about Cavani being transfer listed, and picking Juve over Madrid/Chelsea/Bayern whoever
This is about a hypothetical situation where Cavani has 2 choices. Stay at PSG or come to Juve in a Pogba swap deal
So, just to make this post absolutely full-proof. This is NOT about us beating clubs to Cavanis signature. Of course he won't pick us over other clubs who offer a similar wage to his current one. This is about PSG offering us Cavani in exchange for Pogba, otherwise he would not be for sale at all. In this scenario, Cavani has two choices. He can continue to play out of position to accomodate Ibra (He's allegedly unhappy with this) OR he COULD come to Juve and take a small pay cut.
