So, Callum McGregor ensures Ronny Deila's Celtic tenure gets off to a winning start in his first competitive game.

The narrow win in Iceland puts them in the driving seat for their Champions League second round second leg qualifier against KR Reykjavik.

Celtic will aim to finish the job at their temporary new home at Murrayfield next Tuesday.

Thanks for your company tonight. We're back on Thursday to mark Scottish interest in the Europa League qualifiers, hope you can join us then. Cheers.

Celtic boss Ronny Deila

"We created a lot and deserved a goal; maybe a couple more. I would've been happy with zero zero. My philosophy is to learn and get better every day. It's important for us to play matches."

John McEnerney: "A win is a win. Celtic will be happy to a point, big improvement needed for second leg; don't need any surprises in Murrayfield!"

With time running out in Reykjavik and the Champions League second round qualifier seemingly heading for a goalless draw, youngster Callum McGregor weaved his magic on the right before finding the net for a debut goal.

"Ronny Deila has spoken to [assistant boss] John Collins and they like this 4-2-3-1 system. He might stick with it..."

Tom Watson: "The goals are bigger at Murrayfield, so maybe a few more goals in the return leg..."

BBC Sportsound pundit Chick Young

"Kris Commons was the one player who lit up the game and Celtic can tick the 'job done' box."

Celtic are denied by the woodwork on three occasions but not victory in Ronny Deila's first competitive game in charge. Callum McGregor's late goal securing the win against an obdurate KR Reykjavik.

Scotland assistant boss Mark McGhee

"Going through the Celtic team, there have been few disappointments."

Former Celtic striker John Hartson

"Young McGregor for Celtic.. Away goal vital, strolled the game could have scored 4-5 tonight. Can see them going through comfortable."

BBC Scotland's Giancarlo Rinaldi

"Who Shot KR? Callum McGregor, eventually!"

Celtic push for a second and Stefan Johansen finds Mikael Lustig with an accurate diagonal ball but the Swede is flagged offside.

Three minutes plus added time remaining in Reykjavik.

It's been coming. Celtic's incessant pressure finally pays off as Callum McGregor is rewarded for a fine run and dribble on the right, his deflected effort whistles low beyond Magnusson and into the net.

Smiles from Ronny Deila in the dugout as he looks to be on course to mark his first competitive game in charge with a win.

What a chance for the hosts. A dangerous cross into the box splits the statuesque Celtic central defence but Ragnarsson can't nod it past Forster.

Stung into a response, Derk Boerrigter and then Teemu Pukki are denied by the acrobatic Magnusson.

Andy McEnaney: "2 powercuts so far in the Tenerife bar I'm watching this in but no electricity from Celtic."

Have you eclipsed Didier Drogba as the angriest man in flip-flops?

Celtic are denied by the Ninja-like reflexes of goalkeeper Magnusson who thwarts McGregor before Pukki's effort clips the post!

Ronny Deila's side are showing greater urgency but have been unable to find that away goal...

Toniwater: "Celtic coming closer every time! That was a screaming effort by LG, only a matter of time, fresh legs now would do damage 2 KR"

Teemu Pukki and Derk Boerrigter come on for Leigh Griffiths and Anthony Stokes as Celtic seek to break the deadlock in the final 15 minutes.

Celtic defender Virgil van Dijk shows sound awareness to snuff out a Reykjavik attack and clear for a corner. He then gives his team-mates a verbal blast for failing to stop the move further up the pitch.

Ronny Deila is preparing to bring on a couple of substitutes...
