John Toshack was pleased with Wales' 1-0 win over a Basque XI on Sunday but admits his side were often second-best.
Toshack is putting his faith in Wales' next generation
Skipper Ryan Giggs' 75th-minute breakaway goal proved the difference at the Estadio San Mames in Bilbao.
"We had to clear off the line twice so they'll be disappointed, the Euskari, and feel they should have at least drawn or won the game," said the coach.
"But we had chances even when we weren't playing that well and finished the game quite strongly."
Although he did not give a debut to 16-year-old Southampton left-back Gareth Bale, who stayed on the bench, Toshack did manage to field youngsters Joe Ledley and Lewin Nyatanga.
"The result will give particularly some of the younger ones a bit of confidence," Toshack added.
"Once again Nyatanga did okay and Ledley, in a wing-back position a little bit strange to him, did okay as well.
"But we still haven't found the right balance and if we may have to sacrifice a little bit in attack to be more solid.
"It was hard out there but a good work-out, well worthwhile.
"The Basques are good technical players, sound La Liga performers and they did not make it easy for us.
"They could have had a couple early on and have plenty of quality and movement.
"But we matched that, played some neat, controlled football, and it was really rewarding against some very experienced international players who have been playing well in top Spanish football for a long time."
Wales will depart on Thursday to head to Austria, where another friendly against World Cup qualifiers Trinidad and Tobago awaits them next Saturday in Graz.
