Goalless after an uneventful first-half at the Cardiff City Stadium
Neco Williams comes off the bench to score last-minute winner for Wales
Wales 0-0 Bulgaria
Georgi Kostadinov is treated for cramp so the players take the chance to have a drink and a bit of a chat.
We are now back under way with 11 minutes remaining.
Worth remembering I'd written off Finland as a 0-0 draw at this stage as well.
Wales 0-0 Bulgaria
Neco Williams has got forward at every opportunity and has added a real energy to the Wales attack.
Wales 0-0 Bulgaria
So a very welcome 90 minutes for Gareth Bale.
Wales 0-0 Bulgaria

That was not a fully fit David Brooks but it was still great to see.
Wales 0-0 Bulgaria
That's David Brooks' last contribution, he's replaced by Jonny Williams.
Wales 0-0 Bulgaria
Ooof. Wales' best move.
A lovely ball by Gareth Bale across the field, a lovely touch by Daniel James and David Brooks' drive grazes the crossbar.
Wales 0-0 Bulgaria
Jonny Williams is about to come on, so I presume they won't both get 90 minutes.
Wales 0-0 Bulgaria
I have just worked out that Wales will now give either David Brooks or Gareth Bale the full 90 minutes.
Wales 0-0 Bulgaria
Spas Delev, who started against the Republic of Ireland, is on to replace Galin Ivanov.
Wales 0-0 Bulgaria
Well worked move from Wales, Daniel James combines with David Brooks and fires at Georgi Georgiev who is able to save.
Wales 0-0 Bulgaria
Neco Williams and Gareth Bale combine well down the Wales right.
How many times are we going to say that in the future?
A lot; would be my guess.
Wales 0-0 Bulgaria
Connor Roberts comes off for Neco Williams who makes his home debut for Wales in his natural position of right back.
He came on in Helsinki as a right winger.
Wales 0-0 Bulgaria
A first effort on goal for Bulgaria as Yanis Karabelyov heads over from a freekick, under pressure from Ben Davies.
Wales 0-0 Bulgaria
Hal. Robson.
Hal. Robson-Kanu.
He's back.
After three years, HRK is back in a Wales shirt as he replaces Kieffer Moore, who had a frustrating afternoon.
Wales 0-0 Bulgaria
Matt Smith goes into the book.
Wales 0-0 Bulgaria
Wales' best spell of the match.
David James finds Gareth Bale after a nice interchange with David Books, but his shot is blocked.
Wales 0-0 Bulgaria

Wales 0-0 Bulgaria
A lovely Wales move is ended abruptly by a terrible, wayward pass by Gareth Bale.
Not something you can say often, or ever.
Wales 0-0 Bulgaria

BBC Sport Wales at Cardiff City Stadium
Kieffer Moore doesn't get much from referees, does he?
Former Wales striker Iwan Roberts is commentating for BBC Radio Cymru sat a few seats away from me and, as a former big centre-forward who used to relish heading the ball like Moore, he has some sympathy for the Wales striker.
Wales 0-0 Bulgaria
David Brooks drifts a freekick in that is too close to goalkeeper Georgi Georgiev and Kieffer Moore barges the goalkeeper like it's 1960 and he is Bobby Smith and he's obviously never getting away with that one.
Wales are much-improved though and look livelier.
