John Toshack criticised the match officials after Wales' 2-1 defeat to the Czech Republic in Teplice.
David Lafata and Jan Koller celebrate the win over Wales
David Lafata was offside as he headed the Czech's opener, then referee Jonas Eriksson allowed a crucial free-kick to be taken with a rolling ball.
"Their lad had only one defender between himself and the goal but I was also angry with their second," he said.
"The rules say free-kicks must be taken when the ball is still, you can't throw it forward to roll and take the kick."
But Toshack was also unhappy with the reaction he got from Eriksson when he questioned the official after the Euro 2008 qualifier.
"The referee was right on top of it and I pointed it out to him and he just nodded his head," Toshack added.
"I was annoyed with that and the performance of the linesman near to the incident."
A Martin Jiranek own goal seemed to have rescued a point for Wales before Lafata struck his second goal in the final moments.
I was surprised with how much Wales defended
Czech Republic coach Karel Bruckner
"It was a cruel defeat - we had worked so hard and defended well," Toshack said.
"We missed a couple of very good chances, but I have some sympathy for Craig Bellamy who missed them both.
"He had been in bed for 24 hours before the game with a temperature and only just managed to play the match.
"Mark Delaney was also not too well, but he also managed to play. I do not want this to sound like clutching at straws, but I felt our spirit and effort deserved more.
"But if you pull back to 1-1 away from home in the 86th-minute, by hook or by crook you've got to hang on or even go on and get a second one yourself.
"They were bad goals for us to concede and they're very despondent in the dressing room - a few of them are young lads and it's very disappointing for them to lose in that manner."
One of those youngsters, Derby defender Lewin Nyatanga, was devastated after conceding the last-minute goal.
"I thought we could tame them, they didn't seem to be causing us too many problems but then came one cross and one knockdown," said the 18-year-old.
"I'm really devastated to let that goal in at the end. But we played well, we can take positives out of that."
The Czechs are also rebuilding after bowing out of the World Cup at the group stage and the retirement of stalwarts Pavel Nedved and Karel Poborsky
Czech Republic coach Karel Bruckner said of his new-look side's late show: "This is a new era for us after the way the World Cup went and the players who are now missing.
"We took time to get going but in the end played well, this team will improve as the games in this group continue. I have great faith and expectation in them.
"We knew Wales would be strong opponents but I was surprised with how much they defended. We spent a lot of time in their half."
