Mateusz Klich has committed a couple of niggly fouls now.

If he keeps that up he will Klich and collect the game's first yellow card.

A first sniff for Robert Lewandowski, but his shot deflects wide for a corner.

Wales clear.

A warning sign though.

Better possession from Wales culminates in Dylan Levitt having a shot from 25-yards, but debutant Kamil Grabara makes the save.

The pitch looks a little soft, almost doughy in the way the ball bounces.

A couple of early Wales passes have been underhit as a result.

'Piotr Zielinski of Napoli.' I've introduced him like he's royalty there.

He is a good player mind.

He should have scored, lovely little ball in from Klich.

I get the feeling the Wales defenders are more worried by Lewandowski and left Zielinski free.

He's a very good player, he'll be disappointed with that end result.

Little chance for Wales, massive chance for Poland.

The marking simply isn't good enough and Piotr Zielinski of Napoli heads wide, totally unmarked, from eight yards.

It was a good ball in with Kieffer Moore getting in on that far stick.

It was a just a bit too heavy for him, he couldn't get over it but a good move for Wales.

First sniff for Wales, but Kieffer Moore heads wide from a difficult angle at the back post.

We had a false start on the kick-off.

Calling Rade Obrenovic as fussy already.

We are now under way.

Kieffer Moore is already making his presence felt.

The Polish crowd are in fine voice.

Fair play to him getting a cap at his age it's fantastic, he's had a great season and he'll slot right into this system that Wales play.

Speaking ahead of kick-off, Wales manager Rob Page told S4C: "Wes has been in this system before and it goes to show he's not forgotten about and he's impressed every member of staff, he'll grab the opportunity with both hands.

"This is an important game but we have to think of Sunday as well.

"I said coming into camp we need a big squad because of the number of games and quality of opposition.

"It's a bonkers month but one we relish. It's about creating a winning team for now and for years to come."

It'll be massive, first time since 1998, a massive achievement and another achievement for Steve Clarke and his team [if they qualify].

If Ukraine do get through Wales will face all the same problems as Scotland with the world hoping Ukraine win!

It's a game of football Scotland need to win, they're in a great place, eight games unbeaten and they'll want to continue that.

You'll hear the Tartan Army belting out their voices tonight as they've been given the lyrics to the Ukranian national anthem.

Ukraine legend Andriy Shevchenko says tonight's World Cup play-off semi-final against Scotland is "much more than football for us right now".

Ukraine are bidding to reach a second World Cup since independence in 1991.

Originally set for 24 March, the match was moved by world governing body Fifa following Russia's invasion of Ukraine.

"The Scotland match is the hope of the country," the former Chelsea striker, who managed the national team at Euro 2020, told BBC Sport.

"Going to the World Cup is very important for Ukraine right now.

"The motivation is incredible. In my opinion, we need to put the result away and just focus on the game.

"We need to play for the fans, for the whole of Ukraine, for those at home, for those defending the country and for those who left the country."

The winners of the game in Glasgow will face Wales in Cardiff on Sunday for a place at November's World Cup in Qatar.
