That's all from me. Please join us again tomorrow for live coverage of Apollon Limassol v Aberdeen, with the Dons leading 2-1 in that Europa League qualifying tie.
Celtic manager Brendan Rodgers: "Big performance. To play that way was sensational. It was a great victory for us.
"James Forrest gets his goal from wide but did a great job centrally. It's a huge credit to the players.
"We haven't conceded a goal. I was fairly comfortable with that set-up and how we defended and I was particularly pleased when we got the goal. After that, they never had any chances, Rosenborg.
"When the draw comes, it's going to be one of those anxious moments again over the two legs. Whoever we get, it'll be a tough game."Copyright: SNS
Rosenborg manager Kare Ingebrigtsen: "I thought we had too much respect for the first 45 minutes. They didn't create that much. We didn't test them at all.
"We came out [in the second half], put some pressure on them. In the best period of our game, they scored a goal.
"Small margins decided this game but we knew that it was going to be close.
"We should've scored a goal in Glasgow, that's where we lost it. We had the bigger chances in Glasgow."

Rosenborg look a beaten side.
Celtic hold on to the ball well, much to the hosts' frustration and even when Rosenborg get it, they are vulnerable to the visitors' counter-attacks.

Rosenborg continue to press but they are not finding a way through.
Celtic look comfortable now. Rosenborg have tired. They are seeing enough of the ball but they are hurried and hesitant.
