I think it's more Bielsa refuses to park the bus and will go for teams, even the "big 6". Whilst they got hammered, they could have easily scored a few more themselves.
They'll be upper midtable at least and quite dangerous next season if he gets properly backed.
I think there has got to be a balance between parking the bus and defending like a school team, particularly when you're away at united. As you say they created a fair few chances themselves with a bit of half decent defending (particularly from set pieces) they could have easily got a draw, if not snatched all 3 points as united haven't been great at home.
At some point you've got to admit its ridiculously naive.
Like I say though they're short at the back, they have defended pretty well in some games so it'll be interesting to see what happens with them. I think they could slump big style 2nd half of the season.
