Three-and-a-half European games completed so far and no Northern Irish side has yet managed to score a goal.

There's still time for Linfield to alter that this evening but Larne, Crusaders and Derry City all have some work to do in the second legs if they are to salvage their respective ties.

The half-time whistle blows and Emil Atlason's stunning free kick separates the sides.

Setting aside that penalty miss from Chris Shields, Linfield won't be too dissatisfied with the opening 45 minutes and they have shown enough to suggest they can still get a positive result from this first leg.

Joel Cooper spins and fires a shot over the bar but Linfield are finishing this half on the front foot.

There will be two minutes of additional time at the end of this first half.

Linfield force a flurry of corners as the half comes to close.

Can the visitors make their pressure count?

It's that man Atlason with another effort for Stjarnan.

This time he tries to curl an effort from outside the penalty area but it lacks the pace and direction to really trouble Chris Johns.

Stjarnan go close again as goalscorer Emil Atlason almost adds a second.

He arrives to meet a corner but his side-footed effort goes wide of the mark.

Atlason looks a handful, though - the star man for Stjarnan, you might say.

Linfield haven't crumbled after that penalty miss and they are steadily starting to gain a foothold in this game but they haven't really troubled the Stjarnan goalkeeper as yet.

Chris Shields goes straight up the middle from the penalty spot but his effort shudders off the underside of the crossbar before being cleared.

The kick was awarded after Scot Whiteside nodded down Chris Johns' long free kick and Kyle McClean nicked in front of Kjartan Kjartansson who brought him down.

Penalty to Linfield...

Scot Whiteside collects the first yellow card of the evening for a mistimed challenge on Orvar Eggertsson.

It's a dangerous area for the free kick as well.

It's all over at Nantporth Stadium.

The Cymru Premier side will bring a two goal advantage to Seaview next week.

An injury concern for Linfield as Joel Cooper slips and falls heavily on the artificial surface.

He's up and moving again - albeit a bit gingerly - holding his lower back.

Caernarfon Town are closing the away side's attack down any time they push into the box.

One minute to go...

There will be four minutes of additional time.

Will we see another goal?

James Teelan's header looks like it's on target, but Danny Gosset clears the danger on it's route towards goal.

Caernarfon are defending superbly as Crusaders attempt to increase the tempo in the final five minutes.

A rare attacking foray from Linfield sees them patiently work an opening outside the penalty area.

The ball is rolled back to Kirk Millar but he fires his shot well over the crossbar.

He can't as he sends his effort well wide.

Morgan Owen brings Stewart Nixon down on the edge of the box and Crusaders now have a free-kick in a very good position.

It looks like Nixon is going to take it - can he make it count?
