Around 500 Celtic fans made it to the match with Rosenborg and got their reward 68 minutes into the match.
It seemed that James Forrest had initially stumbled on the ball with his first touch but there was no doubting his shot as he smacked the ball high into the net.
The Rosenborg keeper didn’t get a look in but the Celtic fans had a perfect view as the ball flew into the net as the hoops took their place in tomorrow’s play-off draw.
In other circumstances the closing 20 minutes could have been a nerve-shredder but not with this Celtic side.

Forrest could have scored a second, Griffiths and others had chances as Celtic booked their place without any drama.
