Not even slightly, and I've already explained it to you so that's why I'm convinced you are trolling.
Evra is forcing the move through. It's got nothing to do with "we let him go, you let him go".
Plus, the deal is £2m. Vidal is valued at £30m+ so it in no way could possibly hinge on the Evra deal. Juve could simply walk away if that was the case as it would be a laughable proposition.
Evra has penned a goodbye letter to United fans, agreed personal terms etc whereas there hasn't even been a bid for Vidal from United.
Conte's resignation was unexpected, so I imagine Juve wanted to get his replacement in (Allegri) and have him give the go ahead as well (like Sven/Hughes and Jo, or Hughes/Mancini and Dzeko)
