Warren Gatland was left frustrated by his side's error count after Wales lost to Ireland in their first World Cup warm-up.
Wales were outplayed with late tries from Justin Tipuric and Alex Cuthbert flattering the scoreline in Cardiff.
"We'll have a good look at the tape but I'm disappointed with the number of turnovers. We played better after the break and scored some nice tries but you can't go out and make that many turnovers, especially against Ireland, and to give them soft points," said Gatland.
"The challenge for us is working on the depth of our squad and giving players an opporutnity to get up to a certain level. We just didn't play that well in the first half and made it easy for them.
Gatland revealed that Wales would reduce the squad to either 36 or 38 towards the end of next week and praised the performances of Justin Tipuric, Taulupe Faletau and Matthew Morgan's "spark" off the bench.
"This was a big chance for a lot of players to perform. I thought Ross Moriarty was OK and the yellow card was a bit unlucky, but I thought he played pretty well and had some good carries and good footwork," he added.
"The two half-backs who came on did very well – Gareth Anscombe played nice and flat to the line.
"It was tough for Tyler [Morgan] and he will have learned a lot. He was unlucky with a couple of offloads and didn't get a lot of chances. For the young boys it's often hard out there – I remember Jon Davies was like a rabbit in headlights in his first game against Australia."
Gatland added that Ireland didn't spring any surprises but admitted their style of play was effective.
"They have a template that works well with one-pass rugby in your 22 and applying pressure at the breakdown. It wasn't anything different to what we've seen before and they didn't play a huge amount of rugby, but they played the territory well.
"It was frustrating at the breakdown with the number of penalties they gave away with eventually a yellow card coming late on, but in fairness they got away with that and it slowed the ball down and frustrated us."
