John Toshack admitted that his youthful Wales side were made to 'suffer' by a German team who cruised to a convincing 2-0 victory in Cardiff.
The Wales boss saw Germany captain Miroslav Klose score a goal in each half at the Millennium Stadium to virtually secure the Germans' progress into next summer's Euro 2008 finals.
But for Toshack it was a bitterly disappointing evening, which got off to a bad start when skipper Craig Bellamy pulled out because of his young daughter's sickness.
Bellamy has spent the last two days and nights at the hospital bedside of his third child, who was born on Monday.
Now Toshack will give Bellamy until tomorrow's early evening training session at their Vale of Glamorgan base before deciding whether to take the West Ham striker to Slovakia for Wednesday's qualifying clash.
Wales have already called up Wycombe striker Jermaine Easter as cover.
Toshack said: 'We lost Craig very late. I was with him at his house on Friday evening and he clearly had some problems. He had not eaten much or had any sleep.
'Everyone knows that Craig will play for Wales come hell or high water. But he had a setback today with complications over his new daughter and he was in no fit condition to play.
'We just hope things clear up soon for him to be able to return to playing.'
Toshack added: 'It was a body blow to us before the game, and almost from the start I could see that things were not going the way we wanted.
'Germany are one of the best teams in the world and they really made us suffer.
'We decided to stick with the system that produced last month's win in Bulgaria, just putting three new players into the rolls. But it did not suit them, we had immediate difficulties and we had plenty of problems through the centre of midfield.
'One or two people could have done better, I am very disappointed with the outcome. Germany had more quality and were physically stronger. I have no complaints about the result.'
Toshack has also added David Vaughan, David Edwards and Neil Eardley to the squad that leaves on Monday afternoon for Bratislava.
Germany coach Joachim Low was delighted with his side, who have now lost only once since finishing third in the World Cup finals last summer.
He said: 'I am 100% content and satisfied with the result, usually when we come to Wales we do not win, but this time we fully deserved the victory.
'We played excellent football right from the start, and my only complaint was that we took our foot off the accelerator too early, otherwise we could have scored more.
'But there were times that we were circulating the ball so well and so quickly, Wales could not even get a touch of it.
'With the Republic of Ireland only drawing we are now in a very rosy situation in the group and have taken a big step towards the finals. We now know what we are capable of and what our strengths are.'
