It will be interesting to see how Vikingur respond to being behind for the first time in the tie.

All the momentum appears to be with Linfield at present.

Kieran Offord scores a sumptuous goal to put Linfield ahead on the night.

I was disappointed that Offord didn't bury that but you will take that anyway you can.

The home side aren't settling for the advantage they already have after the first leg and are pushing to break the deadlock tonight.

Brenner is the latest to have a go, but his shot from the back post is wide.

Kyle McClean tries his luck from distance but his shot sails over the crossbar.

Linfield are keeping up the attacking momentum since that superb Offord goal.

Matthew Fitzpatrick emerges from a tangle with Ari Olsen with the ball still at his feet but his shot from a narrow angle is straight at Bardur Reynatreo.

Linfield strike the woodwork twice in the space of a minute as Offord unleashes another piledriver - this time with his left foot - which strikes the underside of the bar before bouncing out.

The VAR official is content that the ball didn't bounce over the goal-line and the game continues.

Almost a second for Linfield as Charlie Allen works half a yard of space but his strike deflects off the base of the post before being cleared.

It really did take something special for Linfield to go in front as Vikingur were really disciplined. There was only one thing on Offord's mind when he got the ball, what a screamer. Vikingur will be disappointed by the defending but what a strike.

Kirk Millar crosses from the right and Ben Hall meets the delivery with a strong header but it's straight at the goalkeeper.

That is a huge let-off, Johansen is causing real problems.

We're under way at the Estadio de Sao Miguel!

Can Larne produce an impressive comeback and advance to the play-offs?

Give this post a thumbs up if you think so or react the other way if you think the home side will extend their lead tonight.

Another good counter-attack from Vikingur as left-back Ingi Jonhardsson - scorer of the winning goal last week - combines with Jakup Johansen, who trundles his shot just wide of the post.

At the other end, a less positive contribution from Ari Olsen as he is booked for pulling back Kieran Offord.

Close for the visitors who work an opening on the edge of the penalty area before laying the ball off to right-back Ario Olsen.

He rattles a shot on goal but Sam Roscoe flings himself to block the ball behind for a corner.

Jakup Johansen chases a seemigly lost cause as Vikingur pump a high ball forward but the striker holds off Ben Hall and forces his way into the penalty area where his shot is comfortably saved by Chris Johns.

Nevertheless, it's a warning for the Blues that the visitors possess a threat on the counter-attack.

A couple of early corners come to nothing for Linfield but manager David Healy will be pleased that the Blues have started on the front foot.

That is a super save by the goalkeeper but this is an excellent start by Linfield.
