^ I agree.
I was going to say, and this goes a bit counter to what I have also perceived as a lack of concetration, that at times our players seem to be so anxious at not conceeding, that they follow the play so closely, that what they end up doing is ball watching, you see them all staring in the direction of the play, forgetting to be mindfull of the players around them, and so often leaving space and/or compleltely open players.
