Switzerland are looking very comfortable in possession - they just wait their chance. They have 25 or 30 passes and then look for the killer ball. We're letting them play in front of us. Hopefully we can break on them.

We started brightly but they grew into the game.

Switzerland have had 70% possession and all the threat but Northern Ireland have held firm. Just.

You feel that the home side need something to take to Switzerland for the second leg. They'll need to find something else second half to get it.

Northern Ireland get lucky.

Stephan Lichtsteiner is in, in the box following as flick header but he loses his footing and stumbles. Replays show he was offside but the slip saved the linesman making the call.

You have to say the Swiss are looking really threatening going forward. Northern Ireland just to need to hang in here.

The noise inside Windsor Park has been relentless, it’s a phenomenal atmosphere.

Northern Ireland can't keep hold of the ball. Corry Evans wins the ball but then loses it almost instantly. Switzerland are bossing this game in terms of territory and possession.

Jonny Evans has been great this half. He stands tall and anticipates superbly where Stephan Lichtsteiner's pull-back cross is going to go. A chest and a boot later and the ball is away from danger.

Good news. Stuart Dallas is back on. He is not moving well but he is made a stern stuff, the Leeds man.

That'll be a worry as Stuart Dallas has started the game well. He has a good relationship with Chris Brunt down that side. Hopefully he'll be OK to continue.

Bad news. Stuart Dallas is down and struggling. He has taken a few heavy knocks in this first half and may not be able to continue.

Fabian Schar's nasty, lunging tackle early in the game was brutal. A more recent one was better timed but still heavy.

Stuart Dallas has been as good as anyone so far for Northern Ireland. His superb run almost sees him break in down the left but a solid tackle from Fabian Schar halts him.

This time Jonny Evans comes to the rescue. Ricardo Rodríguez's delivery is good, right into the heart of the box, but Evans rises to head away.

Free-kick to Switzerland wide left. They are so sharp on the counter. Seconds after a Northern Ireland cross is cleared they are in home territory and threatening.

Zlatko Dalic must have the golden touch.

The Croatia boss only got the job two days before his country's last World Cup qualifier. Just 48 hours after his appointment he led Croatia to a crucial 2-0 win in Ukraine, beating Ukraine to second in the group by three points.

Just 25 minutes into his second game his side are cruising here. with two goals, 60% possession and Greece have not yet had a shot.

Tickets sorted for Russia lads?

Fair to say that Switzerland are on top. They lead the pass count 162 to 53.

Chris Brunt meets the corner with a decent header, which clears the danger. For now.

Switzerland win a corner. They are looking increasingly dangerous.

All Switzerland at the moment. A cross is hung up into the box but Steven Zuber can't get enough power on his header, which loops out for a goal-kick.

The Swiss want a corner and overstep the line with their protests when one does not come. Granit Xhaka gets a talking to.
