The 'marmite' James Forrest was the hero on the night for Celtic as he fired home the only goal of the game to put a stubborn Rosenborg side to the sword and in turn securing the Scottish champions' place in the Champions League play-off round. Celtic created the better of the chances in the first half but the game remained goalless going in at the break.
Into the second half and Rosenborg came out of the traps looking to secure a quick fire goal to defend, but Celtic held firm despite some nervy moments and they were rewarded with a deserved goal on 69 minutes as Forrest fired the ball home from an acute angle to send the Celtic fans who travelled to Trondheim delirious.
With the game now running away from them Rosenborg pushed forward in the final minutes of the game as they searched for the two goals that would send them through at Celtic's expense. But Rodgers' side held firm to secure their place in the next round where they will face Astana, Qarabag, Rijeka, Hapoel Beer Sheva or Slavia Prague in the play-off round.
Speaking after the game, a delighted Brendan Rodgers said: "The players were absolutely magnificent. It’s a pressure game –you are coming to a team who are the champions of their country with a great history like Rosenborg. And to come and play like we did was so pleasing.
"You can see the players are maturing, to play in a pressure game like that and pass like we did.
"The goal we scored was brilliant - the build-up, the patience and quality, and the goal itself. It was an outstanding performance and the players deserve a huge amount of credit in how they managed the game."
