David Healy makes another change as Chris McKee replaces Kieran Offord.

The Vikingur defenders won't be sorry to see the back of Linfield's Scottish striker.

Matthew Fitzpatrick fires a shot from outside the penalty area but it's wide of the target.

Triple change for the hosts.

Rocha, Matheus Pereira and Wendel Silva are brought on for Pedro Pacheco, Pedro Ferreira and Frederico Venancio.

Fresh legs from Linfield as Sean Brown replaces the industrious Charlie Allen.

Ingi Jonhardsson - the left-back who scored Vikingur's winning goal seven days ago - burst onto a loose ball in the penalty area.

Thankfully, from Linfield's perspective, his effort on this occasion is steered wide of the far post.

Much more threatening from Linfield as Kieran Offord - who has been a real livewire - single-handedly goes at the Vikingur defence before firing a rising shot at the near post which keeper Reynatreo flicks over the crossbar.

Tiarnan O'Connor's strike from 30-yards takes a deflection and curls inches over the crossbar.

That was Larne's first chance of the game but with just under 30 minutes to go, it would have been a great time for them to score!

Vikingur make a hash of clearing a Linfield corner and central defender Ben Hall attempts an overhead kick which flashes off target.

The ball is certainly at the right end of the pitch as far as Linfield are concerned.

Matheus Nunes flicks Serginho's corner narrowly wide of the left hand post.

That was another good chance for Santa Clara.

Neat build-up play involving Josh Archer and Kieran Offord but the midfielder's low cut-back is slightly behind the in-rushing striker.

We're into the final 15 minutes at Windsor Park, where Linfield hold the advantage, albeit a precarious one.

Can the Blues add another goal to secure their passage to the play-off stage?

A double change for Vikingur as Jorgen Nielsen and Stefan Radosavlevic come on for Jakup Johansen and Aron Ellingsgaard.

Pedro Ferreira becomes the first player in the second half to be cautioned.

Goodness me, that would have been a cracking goal!

After some nice build-up play from the home side in midfield, Henrique Pereira finds space 25-yards out and rattles an effort off the crossbar.

The second half has started just like the opening 45 minutes with Santa Clara dominating.

This is a blow for Linfield as goalkeeper Chris Johns hasn't recovered from that knock to the head and he is withdrawn and replaced by David Walsh.

The Blues also bring on Ethan McGee in place of Matty Orr at the same juncture.

Brave defending by Matthew Ridley as he gets in the way of Serginho's effort, which looked like it was heading towards goal.

Ridley is now receiving treatment, but it looks like he will be able to continue.

That is poor and last gasp defending from Linfield. It is an unbelievable stop but one Johns should not have to make. Linfield players need to make sure they are concentrating.

A nervy moment for Linfield as Arnbjarn Svensson gets on the end of a free-kick into the box by Solvi Vatnhamar.

Blues keeper Chris Johns is able to block and is then caught slightly late on the ground by Ingi Arngrimasson, who is cautioned.

The action resumes in Ponta Delgada!

The home side make two changes at the break with Serginho and Gabriel Silva on for Vinicius Lopes and Adriano.

Matthew Orr is down receiving treatment after a block tackle.

Linfield will be happy with the break in play. They've been able to keep Vikingur at arm's length thus far in the second period.
