Just needs closing. As do most of the others. I have a feeling that even if there was a whole thread designated to a joint effort to emulate Barca's tactics like Fmb might do, there would still be umpteen other threads asking the same question.
It´s probably unplayable in fm but if you really want to try then I´d say this is your best shot.
