Vidal is worth the same price as Di Maria. That should be the asking price. Otherwise, enjoy Europa Man U...
That being said I'd only be ok with selling Vidal in the instant that we fully-reinvest the proceeds improve the team vs. what we had with Vidal.
Honestly though, watching Man United in the transfer market is like watching a 10 year old buy penny stocks. They overpay for crap.
Most of the purchases are questionable and add to positions of strength.
Even Di Maria isn't exactly necessary given that in a 3-5-2 Di Maria is most suited as a wingback, which Luke Shaw and Valencia will play.
They need true central midfielders and central defenders.
Herrara is ok
Shaw a stupid purchase.
Di Maria wasn't worth it for the price
When they are willing to fork out that kind of cash and overpay, I wonder why Vidal's bid isn't 100 million euro considering he:
1) Plays the position they need
2) Is one of the best in the world
3) Has played 3 years in a 3-5-2.
