A large part of the pre match discussion about this tie, the second in the space of a year, was mostly about Celtics supposed defensive issues. The other dominating story leading up to this first leg was Rosenborgs decision to sack Kare Ingrebrigtsen after progressing past Valur in the opening Champions League qualifying round.

Jozo Simunovics red card in the second leg win over Alashkert meant a shortage of options to play in the three central defensive positions.
