I am moving towards the stage on a daily basis where I am caring less and less whether Vidal joins us. I mean, he is a great player and the ideal signing for me - but I can't convince myself to believe that everything would then be okay if he were added.
I would put more money on us continuing to be shit for a good while even if we bought Vidal than I would on us becoming very good again.
We would then have at least one of the best first XIs in the league. However, while I know it is very early days, LVG looks no less clueless than Moyes right now, and if we continue this formation and playing players based on names and not plan - I don't see any imminent improvement regardless of who we sign.
The benefit of having Vidal is that he's played 3-5-2 at Juve, that's the standard formation. He's also a leader on the pitch, someone who will take responsibility and bollock players when required. I actually think he'd help LvG significantly.
