Our defence has been absolutely woeful for a long time now. Skrtel, Toure, Agger, Sakho were all at least decent CBs and have all struggled adjusting to Rodgers' system. You just don't suddenly become a bad CB like that. It seems like our whole defensive strategy is to press high and hope for the best. Pressing high only works if the whole team does it which we haven't always done. There's also been the added problem of Mignolet giving his defence the jitters. It's simply not good enough but I don't see it changing. Just got to hope our attack improves so we can do we what we did last year: score early and then afford to put numbers behind the ball and counter-attack.
