Massimiliano Allegri's side have been linked with the Portuguese winger for just about as long as the Red Devils have Vidal, and Anthony Chapman of the Express claims that both may now complete their long-anticipated moves.
It's a story of differing values, as things stand. Vidal is very much one of the Bianconeri's jewels, while Nani has been little more than a fringe player at Old Trafford for several seasons.
New helmsman Louis van Gaal recently indicated that he doesn't rate the wingers currently under his command too highly, according to the Mirror (h/t Sky Sports):
It is a strategy of Manchester United to do that. At this moment, we have five No. 9s and four No.10s – and we don’t have wingers to give us attacking width.
Or, I should say, we don't have wingers of the highest level, like Ronaldo or Di Maria or somebody like that. So, I have to play in another way – and you have seen that already. I only buy when I think we need to buy – in the position that is necessary.
However, it's at times like this that tactics can come into play alongside financial needs, both of which Juve must take into account ahead of the 2014-15 season, with Allegri looking to shake things up in his new setting.
Chapman goes on to claim that a verbal agreement is in place for the South American to pen a five-year deal with United worth wages of £182,000-a-week, speculation between the two parties reaching its most intense stages.
And Daniel Taylor of The Guardian insists that all the rumours this summer aren't for nought regarding Vidal:
Nani's place under Van Gaal is far from being of crucial significance, either. In the new regime, the wide man wouldn't seem a natural fit for the five-man midfield the Dutchman intends to play, not being of the defensive skill set needed to play at wing-back.
Of course, it's also well-founded that Van Gaal will field other formations with a place for more natural flank figures such as Nani, but Vidal plays in a position altogether in more desperate need of reinforcements at Old Trafford.
The Telegraph's Darren Richman does place some faith in the out-of-favour Nani, however, insisting that if he were to receive more first-team chances, the player could yet be a success:
Juve are right to see some value in United's man. After all, Nani is poised to come upon his playing peak at the age of 27, and with Juve more likely to promote a stratagem that nurtures advanced wingers, he could unearth the consistency he's yearned for so long in England.
Marouane Fellaini has become the butt of many a joke since moving to Old Trafford, failing to recapture the form that saw him become an Everton talisman, thanks to tactics being adapted to suit his needs in a more attacking state.
The fit-again Darren Fletcher doesn't add too much more confidence to United's engine room, and although the signing of Ander Herrera has added a new dimension, there's still a steeliness missing at the squad's core.
United may go on to add more wide talent to their ranks this summer, but already Nani sits as a lowly figure in the pecking order, all the more so now that the club's style of play juxtaposes his own.
Vidal, however, wouldn't be up for debate as a figure of worth to the side, and if the financial side of things isn't an issue for the Red Devils, it's a changing of the guard they need not lose sleep over.
