I don't think there's much difference between a 9-0-1 and a 8-1-1 which is basically our current formation. It is just that we are shite.Lindelof and Granqvist looked solid because they played a formation of 9-0-1 (not far from the truth btw). They had 4 midfielders guarding them and the defenders only job was to disrupt play, not keep possession or build up attacks, just hoof the ball anywhere with all their might. Any defender looks good in that, Lindelof did and look at him here now.
