Rosenborg had the better chances against Celtic in their Champions League clash but did not leave Parkhead with an away goal.
Celtic were fortunate to escape their Champions League third qualifying round first-leg clash with Rosenborg with a 0-0 draw as Brendan Rodgers' side produced an unconvincing performance at Parkhead.
The Scottish champions easily dispatched Linfield in the previous round, winning 6-0 on aggregate, but head to the return leg in Norway with this tie still in the balance.
But it could have been much worse for Celtic, who only sporadically threatened and were grateful to Craig Gordon for keeping Rosenborg at bay.
