Will Brendan Rodgers be mulling over a formation change at the break? Scott Sinclair, who has been kept quiet by the Norwegians, will be looking to have a greater impact in the second 45.

"Celtic haven't forced a save out of Andre Hansen. They've had so much possession but haven't forced a save.

"[Scott] Sinclair's been very quiet. If Rosenborg keep defending as well as they are, this could end 0-0.

"Even a one-goal advantage would be a help going over there. Nil-nil is not great."

Much gnashing of teeth in Celtic circles as a frustrating first half draws to a close with the first leg goalless. The absence of Moussa Dembele and Leigh Griffiths is being keenly felt.

A flicker of a chance for Nicklas Bendtner but the former Arsenal man balloons his effort high, wide and out for a throw-in. Ironic cheers from the Celtic supporters; not a great moment for the giant marksman.

It's a case of nearly there on a number of occasions during a frustrating first half for Celtic. However, credit has to be given to Rosenborg who are giving the hosts very little space in which to strut their stuff.

Jose Mourinho must be chuckling somewhere and stroking a white cat...

"Celtic need a lot more from James Forrest. He looks like a player who is struggling with his confidence again. Tried to beat his man earlier and just managed to run into him and give the ball away. Would be a very early move from Brendan Rodgers but bringing on Hayes at half-time might be on his mind right now. Celtic are not asking questions now, They've lost their way in the last 15 minutes."

A promising Celtic move fizzles out as James Forrest challenges for a header somewhat gingerly - as though not wanting to disturb the flowing locks after a visit to his favourite barber's - triggering howls of frustration from the Celtic supporters.

So far, Celtic have kept giant striker Nicklas Bendtner quiet in the first half, without being able to carry a significant threat of their own.

Tom Rogic has been deployed in the Moussa Dembele/Leigh Griffiths role for Celtic tonight in both strikers' absence.

As a regular scorer, the Australian is no stranger to the penalty area but is more accustomed to playing in midfield.

The visitors bare their attacking teeth for the first time in this Champions League qualifier, Konradsen pick-pockets Scott Brown before seeing his rasping drive tipped away by Craig Gordon.

"Celtic playing some nice stuff against a packed Rosenberg defence. Clever build-up play, inviting crosses but the lack of a central striker is a big problem for them. Lustig has curled in a couple of beauties but no Celtic player has been anywhere near them. Rosenborg have had one good chance. They're surviving on scraps of possession but they look fairly dangerous at times when they break forward."

Scott Sinclair earns a free kick following some over zealous tackling by Hedenstad. Scott Brown picks out Jozo Simunovic who in turns feeds Mikael Lustig; the hosts are dinking the ball about in impressive fashion but are they missing the threat of absent strikers Moussa Dembele and Leigh Griffiths?

Kristoffer Ajer, 19, has been given a rare Celtic start tonight and the Norwegian defender has had a quiet game so far with most of the action at the other end of the pitch.

Hang on a minute. Rosenborg spring to life as Konradsen finds Jensen but his efforts is blocked... spins in the air and out for a corner.

Celtic clear their lines from the set-piece but a warning sign for Brendan Rodgers' side.
