People don't see that, Giaccherini didn't track back, Marchisio was staying behind to do the cover even if in the second he was clearly tired, this was his 3rd game in 1 week, his passes were all on target too.
If Giach help the defense a bit it would be far better.
We relied on Marchi alone in defending the midfield since Pirlo looks a bit shaky in defending and Giach too focus on attacking.
