Croatia have got enough quality in the team, it just takes one moment.
The boys have to be on it.

We haven't put a foot wrong.
For me, Kieffer Moore needs to look after the ball a bit better at times, but the attacking play has been good.
Jordan James and Ethan Ampadu have done a fantastic job too.

I think they'll go into half-time with confidence knowing that they've gone close to scoring.
Playing a bit more direct and getting runners in behind, they'll get chances in the second half.

I think you have to adapt sometimes. When you are Wales and you haven't got the high calibre of international player like Croatia, you have to be adaptable.
Wales have done that superbly well tonight.

We've controlled that half.
The shape and structure has been very good. We have to take our chances when we create them.
I think we're unlucky to be going into half-time at 0-0.
HALF-TIME
Wales 0-0 Croatia
That's half-time.
One of the best halves under Rob Page's management from a performance perspective, but still 0-0.
Much to give Wales heart and hope, however.
Let's have a brew, see you in a few.

Harry Wilson, who is probably too young to know who Billy Idol is, but who has come styled like Billy Idol, just came very close to getting on the end of a Kieffer Moore flick-on.
Wilson and David Brooks have been really lively tonight.

I think we've been very positive and we've shown a lot of energy.
We've put Croatia under pressure and created a few chances.

Croatia have been poor by the standards we associate with them.
Wales are sharper and Croatia have really struggled to find space in the final third.
They are also missing the delivery of Ivan Perisic. When they do work the ball wide, possession is being squandered.

Wales haven't worked it out yet but their shape is giving Croatia a real problem.

Some respite for the visitors as they spray the ball around. Almost 70% possession for them, but absolutely no sniff at goal.

Your worry, if you're a Wales fan, and you probably are, is did you need to score in this period of dominance?
Danny Ward could have been watching a boxset for most of this half, but Wales haven't capitalised.

Wales are playing brilliantly.
They've really been on top. It's a lovely strike from Neco Williams.
I thought he was going to slip in Connor Roberts, then he unleashed a great right-footed strike. It's a great save.

Croatia keeper Dominik Livakovic is playing like he did at the World Cup. Two excellent saves so far.
Really encouraging start from Wales. There is a sense of belief coursing around this stadium.
CLOSE!
Wales 0-0 Croatia
Close again for Wales!
Neco Williams wraps his foot around the ball after some slick Wales passing and Dominik
Livakovic again has to get down well to tip the ball around the post.
Kieffer Moore then heads wide from the corner.
Wales well on top in this opening 30 minutes and could be ahead.
Croatia's possession is pedestrian.

We've been good in the past five minutes. We need to score.
We're a real threat from these long throw-ins with Connor Roberts.
Croatia are rattled a bit, I'd say.

David Brooks and Harry Wilson have started well. The two of them bring such elegance and imagination to this Wales side.

I think [Domagoj] Vida is very lucky there.
The only reason it's not a red is because his partner Josko Gvardiol is probably just getting over in time to tackle Harry Wilson if he gets into the box.

A frenetic passage of play. Wales fans howled for a red card for Domagoj Vida, but Josko Gvardiol was there to cover. Think the referee got that one right.
CLOSE!

Lovely free-kick by Harry Wilson, Dominik
Livakovic saves it with his fingertips.
