Callum McGregor scored a debut goal to get Celtic boss Ronny Deila's reign off to a winning start in the Champions League qualifier against KR Reykjavik.

The Scottish champions dominated but had to wait until the last few minutes before 21-year-old midfielder McGregor netted on his first start for the club.

Interview - Celtic manager Ronny Deila

Kris Commons had struck a first-half volley against the bar and Leigh Griffiths did the same after the break.

The return leg of the tie takes place at Murrayfield next week.

The surroundings were modest to say the least but Celtic took to the field at the KR Vollur Stadium hoping this would be the first step on their way to the glamour and riches of the Champions League group stages for the third consecutive season.

The hosts are 11 games into their league campaign and currently sit third in Iceland's top flight. Yet their superior match sharpness was not evident in the opening seconds.

Charlie Mulgrew, captaining Celtic in the absence of the injured Scott Brown, released Griffiths with an inch-perfect through ball but the striker's touch let him down and Stefan Magnusson raced off his line to snuff out the danger.

Griffiths then controlled a high ball brilliantly, lobbed it over the head of a defender and laid off to Commons, who crashed a superb volley against the crossbar.

Scotland's reigning player of the year tried his luck again from distance minutes later and this time Magnusson pushed it past a post.

English striker Gary Martin had the home side's first effort on goal, pouncing on a poor header from Emilio Izaguirre and slapping in a shot that proved no test for England's World Cup goalkeeper Fraser Forster.

Seconds after half-time, Griffiths linked well with Commons again but the latter's right foot curler from 18 yards was just too high.

Commons had further chances as the pressure on the home defence grew but could not seriously trouble the goalkeeper.

Griffiths' thunderous drive did have the beating of Magnusson but it came back off the underside of the bar.

Anthony Stokes and Griffiths made way for Derk Boerrigter and Teemu Pukki as Deila shuffled his pack and the latter became the next Celtic player to hit the frame of the goal.

Magnusson denied Commons and McGregor in quick succession and Pukki struck the outside of a post after latching on to a loose ball.

At the other end, former Celtic youth player Kjartan Finnbogason found himself in acres of space on a rare foray forward for the hosts but was unable to make it count.

Magnusson then saved well from Dutchman Boerrigter before the impressive stopper denied Pukki minutes later.

However, he was unable to prevent Celtic finally breaking through with six minutes to play. McGregor cut inside from the right before firing in a low left-foot shot that took a deflection before nestling in the net.

The goal means Deila's side go into next week's second leg - which will be at Murrayfield with Celtic Park unavailable due to the Commonwealth Games - in a strong position to complete an aggregate victory.
