John Toshack wants his more experienced players 'to step up to the plate' as Wales prepare for the difficult trip to Germany.
His side travel to Germany for Wednesday's crucial World Cup qualifier sitting in second place in Group 4, just a point behind their hosts.
Six under-21s were in the side which beat Liechtenstein 2-0 in Cardiff on Saturday, and Toshack now wants his older players to show the way in what is sure to be a stern test on Wednesday.
He said: "The younger lads have done well. Maybe a few of the older ones can step up to the plate and do a bit more for us.
"We do need our more experienced players to stand up and be counted, to perform well."
Wales recorded a fantastic goalless draw with the Germans in Frankfurt 11 months ago and Toshack would love a repeat performance.
He said: "We will have a look at the video of the game when we drew in Frankfurt last year, assess the opposition and have a real crack at them again.
"If we could get a goalless draw again it will be a terrific result, particularly as Germany did drop a couple of points in an earlier draw with Finland.
"But for a few hours on Saturday we were top until Germany beat Russia. But the higher up the group table we are gives everyone a lift and real confidence.
"We can use that performance in Frankfurt to our advantage. We had five under-21s in the side that night and pulled off a great result."
Toshack is considering the fitness of centre-back James Collins, who got on for 10 minutes as a substitute on Saturday after recovering from a cruciate knee operation.
It was his first senior football of the season, and the Wales boss said: "The difficult one is whether Collins can handle a game like that after so long out.
"Lewin Nyatanga, who has also been out all season, got 90 minutes for the Under-21s on Friday and will be better for it.
"He will be withdrawn from that Under-21 squad for the second-leg against England on Tuesday, that was always the plan, and he will be with us in Germany.
"Last time there we set up with three centre-backs. Well we do have that option now with Ashley Williams, Craig Morgan, Collins and Nyatanga to choose from.
"Craig Bellamy looked OK, fitness-wise, after so long out. He was just disappointed he did not finish with a hat-trick, and he knows that.
"He got 80 minutes in for us, and looked OK. He missed chances but, generally speaking, was fine."
