Coach Larry Previews Barcenal vs Arselona

Firstly, from the Xavi interview, speaking about Spain, but easily parallels Barça:

"Paraguay? What did they do? Built a spectacularly good defensive system and waited for chances – from dead balls. Up it goes, rebound, loose ball. It's harder than people realise when you've got a guy behind you who's two metres tall and right on top of you.
