I just don't see it. Xavi has licence to roam, he's the one that knits it all together and his range of passing is up there with the very best. Lucas might have the odd foray forward but he ususally operates in a specific zone and lacks any sort of incisive passing, short or long. I'd agree that the shape wouldn't be so bad with better players, as we saw with Xabi, but it's still more of a defensive minded set up compared to the one Barca employ.
