The idea behind it is sound - and it's worked well for us most of the season. Most teams play one striker, your centre backs split and go wide, the striker can only press one of them so the keeper goes to either the other centre back or into midfield and takes the striker out of the game. If you play it to the centre back, the opposition midfield will inevitably press them which opens up the pass into midfield.
Obviously the intention isn't to play a blind pass.
Where it went wrong last night was that they played with two strikers, one winger who stayed wide and one who drifted in, and they pressed us high up the pitch, therefore splitting the centre backs didn't really work as they always had players pressing each of the three options. Then an element of complacency - Alderete not looking up and playing the blind pass into the centre of the pitch, Roefs not anticipating that Wood was closing him down. And then a lack of common sense - if you press the defence with 4-5 players you're going to leave gaps in the your own half, if only we had a striker who can hold the ball up and pin defenders back eh?
It doesn't need binning off but we can't afford to let our concentration drop at this level. Le Bris talks about players finding solutions a lot and they need to be more flexible when certain situations occur in games.
