There's nothing more painful than watching his highlight videos, especially farewell the one Colosimo99 put together recently. You just can't get a terrier of midfield like this anywhere, a 12th man on the field. Nainngolan comes closest I reckon. Vidal is better, and his positivity on the field is sooo infectious, he's a real rarity in that sense.
Losing Tevez, Pirlo and Vidal all in one hit, don't think many teams out there can deal with that kind of loss without being severely effected.
