So here come lots of subs to knock that on the head.

Belgium 2-1 Wales
Clever freekick routine from Belgium, but Youri Tielemans' shot deflects wide off Neco Williams.
YELLOW CARD
Belgium 2-1 Wales
Ethan Ampadu is booked for tagging back Eden Hazard.
His second booking of the campaign also.

Former Cardiff and Wales defender on BBC Radio Wales
Tactically Robert Page has made adjustments at half-time.
Matt Smith is staying alongside Ethan Ampadu and we are looking to press as a proper front three.
It's been a brilliant start to the second half from Wales - game on.

Wales are looking much sharper after the break.
Credit to them, because they looked completely beaten as we approached half-time.

Kevin De Bruyne is showing a little frustration.
He is starting to think this team just won't go away.
They do it all the time against Belgium, it seems.

That's an absolutely brilliant goal.
Brennan Johnson does brilliantly, skips past players and then clips a beautiful ball to the back post and it's classic Kieffer Moore.
He gets above defenders and the keeper has no chance.

Belgium 2-1 Wales
Excellent composure there from Brennan Johnson.
For the first time he exposed the obvious lack of pace in the Belgium defence with a brilliant turn and run and his cross was absolutely perfect.
GOAL - Belgium 2-1 Wales
Kieffer Moore
Wales are back into things!
Brennan Johnson puts on the burners, crosses brilliantly and Kieffer Moore wins his header - of course he does - and Thibaut Courtois can't keep it out.
Game on.

YELLOW CARD
Belgium 2-0 Wales
Chris Mepham hacks down Eden Hazard and that's him out of the Poland match on Sunday, as he will be suspended.

I think Rob Page will have said at half-time we need to tactically shape up a bit, himself included.
I am watching him and he is getting frustrated.
Post update
Belgium 2-0 Wales
That's about as much culture as I can provide.
No substitutions by Wales by the way, which surprises, because they looked a tactical mess before the break.
KICK-OFF
Belgium 2-0 Wales
We are back under way in Brussels, the birth place of Audrey Hepburn.

Jayne Ludlow
Former Wales manager on BBC Radio Wales
There's a lot to admire from Belgium but we are probably playing into their hands a little bit.
Our pressing game has been one of the things we have done well in the last few years but it's not quite right tonight.
It will be interesting to see now if the boss drops us a bit deeper. We are giving them so much space and time and making them look even better than they are.
Former Cardiff and Wales defender on BBC Radio Wales
Apart from the opening five or six minutes, it's probably been the worst performance I have seen from a Wales team for a long time.
Belgium ask different questions of you with their movement and quality and we really have been found wanting.
I think you saw players not understanding who they should be marking, their roles and responsibilities.
Kevin De Bruyne... it's been an absolute masterclass, but Wales have made it easy for him.

Wales need to be careful. This could become a training session.
It's tactical for Robert Page now. He really has to pull the boys together.
The back five and the boys up front are really struggling with the system.

Wales don't often get hammered - they have a knack of finding ways to stay in games - but this was always going to have the potential of getting messy.
HALF-TIME - Belgium 2-0 Wales
No added on time.
Wales will be very grateful.
They are 2-0 down and that flatters them.
