Boss Brendan Rodgers believes the clean sheet Celtic take into their Champions League qualifier against Rosenborg on Wednesday night could be crucial.

Rosenborg 2 - 1 Dundalk (a.e.t - Rosenborg win 3-2 on agg.) Matthias Vilhjalmsson’s header in extra-time and the top of the crossbar denied Dundalk a stunning result against Rosenborg at the Lerkendal Stadion last night as their European dreams came to a cruel end in Norway.
