"You get the feeling that both sets of players would happily shake hands and be on their merry way here. Stjarnan having a nibble now and then but they know it's all over."
Celtic are playing with much more confidence and fluency now. Stjarnan look tired with over half an hour still to play.
Celtic have made their fist change of the evening. Efe Ambrose is on for Mikael Lustig.

"Tie over. Charlie Mulgrew's clinical finish means it's all over for the home side. They have a very long 40 minutes ahead. The Silverspoons are still singing away!"
And that should be that. Charlie Mulgrew receives a square pass from Scott Brown and drives a low, sliding shot into the right-hand corner. Tie over.
Halldor Bjornsson has replaced Arnar Mar Bjorgvinsson for Stjarnan for this second half.
The second half begins with Stjarnan kicking off.

"Celtic comfortable at the break following that early scare. Barring a complete collapse, they'll be going through to the next round."
Celtic remain on course for the Champions League third qualifying round after Nir Bitton cancelled out Olafur Karl Finsen's opener for Stjarnan on the night.
Brazilian Reynaldo has given Azerbaijan's Qarabag the advantage and an away goal against Montenegro's Rudar Pljevlja. As things stand Celtic will play Qarabag in the Champions League third qualifying round.

"That Bitton goal means Stjarnan now need three without reply here in Iceland. Will they come out and have a go or opt for damage limitation?"
Stuart Armstrong flicks up Gary Mackay-Steven's reverse pass and hooks a shot narrowly wide of the Stjarnan goal.
That Nir Bitton goal means there will not be an extra-time in Iceland tonight. Stjarnan now need to score three without reply to reach the next round, giving Celtic a healthy advantage.
It's been coming and Celtic restore their two-goal advantage and bag an away goal in the process as Nir Bitton gets to Stefan Johansen's corner before goalkeeper Gunnar Nielsen to head into an empty net.
