Wales manager John Toshack and captain Craig Bellamy have both called for a major improvement ahead of Wednesday night's World Cup qualifier with Germany in Cardiff.
The Welsh face one of the toughest sides in the world, just four days after the disastrous 2-0 home defeat by Finland that virtually ended all hope of qualifying for South Africa next year.
Bellamy stood by his outburst at the weekend when he produced a savage tirade at an under-achieving squad, saying: "I stand by what I said after the game. Maybe I could have chosen my words differently, but I still very much believe in what I said. I could have worded it differently, but I have to put up with that."
He added: "Sometimes you cannot be honest in football, you have to duck questions and be as diplomatic as you can.
"But for me that is now easy. I am emotional and I try to be honest as much as I can. Basically I do not like letting people off.
"We were all disappointed and frustrated, and I say things. I am old enough to know that such comments allow people to have a dig back, but I can handle that."
The Manchester City forward added: "We must do a lot better now than we did against Finland. Whatever the tactics and formations, you still have to perform to the best of your ability."
Despite his obvious discontent, Bellamy retains his support for Toshack.
"He is the manager, he believes how we go forward and he has been very good to me. I am very much behind him and the way he does things," he said.
