Neil Lennon ordered his fragile Celtic defence to tighten up rapidly because they are not only costing their team much-needed title points but also draining confidence. The Hoops dropped another two points at Pittodrie after another day of backline blunders that saw them gift two penalties in the 3-3 draw.Celtic have lost to Rangers and AC Milan and have now conceded eight goals in three games and Lennon has accepted that is just not good enough.
