A lot of what we try to do doesn't look natural or fluid.
We did well to get a few chances, but analytically, we didn't deserve much. We lost most 50-50's; passing was very, very sloppy. Rooney doesn't hold up the ball that well. Movement off the ball doesn't present many passing opportunities to keep possession. We're closer to full strength than Barca, which is a little worrying, because if they had Messi, Neymar, Rakitic, Mascherano, new signings et al, they'd have punished us.
I don't think LvG will be too happy with the exception of the actual scoreline. He likes to control games and although they're sloppy enough to be countered, we're not doing enough to limit our passing errors (which are many).
