Run through that list of attributes you gave for Vidal. I read that post earlier today, but I remember defensive presence/tackling ability, boundless running/energy, total team guy/positive morale, flashes of athleticism that result in offence -- I'm thinking back heel pass to Carlitos/bicycle kick goal type highlights from Asa. If he's healthy, Kwadwo fits the bill.
No, he's not the best B2B midfielder in the world, but he can do a lot of the same things Arturo does, and if he's healthy, he will contribute at a very high standard.
