A hostile and pumped up atmosphere no doubt awaits the Blues, but Davies is confident his young guns can again fire after the manner in which they performed in Round 3.
"The forwards are young and exciting," he said. "When you think about where we started 18 months ago, they are coming through really well.
"They are still only young and aged 22 and 23. Sam Hobbs and Macauley Cook are still young lads but were so impressive.
"Macauley was still playing second row when I came here and Sam had his injuries. But now they are having more opportunities and are getting better.
"Young Ellis Jenkins comes onto the field last week and you also have Luke Hamilton who is only 21. It's invaluable experience for them and now it's a case of keeping them and adding quality to those guys so we can become even stronger.
"We have been boosted by the collective effort of the players. It's great to have players like Alex Cuthbert, Leigh Halfpenny and Lloyd Williams back. But it's about the team and individuals do well in a strong team."
Meanwhile, Davis has revealed he may need to shuffle his back line for the clash with centre Dafydd Hewitt a doubt.
"Dafydd has taken a bang on the shoulder so we may need to reshuffle. It's not finalised yet and we have options. We will look at the best combination for us," said Davies.
"We have got a lot of players out injured, but those who have been in have been fantastic.
"It's about developing a squad and at the moment this group has really stepped up. When we have a fully fit squad we will be better for this experience."
