I'm aware there is a lot more to tactics than the formation (I had a rant not long ago about folk being over simplistic in that regard), but it is very tough to look at in more detailed stuff without knowing what instructions are being given.
I believe that most of the problems are being caused by individual errors (defenders giving away endless stupid fouls, midfielders failing to make simple passes, strikers missing open goals), rather than the shape of the team or the pattern of play.
The pattern of play is far from perfect, but I put a lot of that down to adjusting to various new systems and not being able to pick the same players regularly.
Take last nights game: Ferrara, after the game, said he was annoyed about the defenders giving away so many freekicks because he had specifically warned them about how good Bordeaux are at set pieces. The players (mostly Caceres) did not heed his advice and the team paid for it.
