Ange Postecoglou admits Celtic lacked clinical edge and composure as they were bashed by Bodo/Glimt.
But the Parkhead boss is adamant his team can recapture their lethal touch and stage a storming second-leg recovery in Norway.
Postecoglou was left to rue lack of punch at both ends of the pitch as his team were sunk 3-1 by the impressive visitors.
