Yet Cherry and Whites boss Davies has every faith that his men can recover from that reverse - the third league defeat in five matches - by overcoming the French giants at Kingsholm.
Davies said: "Everyone is hugely frustrated with that performance, but the team is better than that, far better than that - I absolutely believe that. It's all my responsibility, and I will pick the players up.
"We bounced back from the first two games of the season and we bounced back really well. And I expect the same thing to happen again. One thing we've done constantly in my time here is we've bounced back from defeat.
"When you've got momentum things are easier and we've got to generate it all over again. I'm very positive about this group of players, sometimes more so than they are in themselves - and that's something we'll address too."
This is the third Heineken Cup meeting between the sides with both clubs recording a win apiece back in 2002. Gloucester's Olly Morgan has been forced to retire from the game while Perpignan lock Luke Charteris could return for his first game of 2013 following a knee injury.
The giant Wales forward, capped 40 times, made his comeback in a 40-minute display for the Catalans' development side last weekend and the 30-year-old has not suffered any adverse reaction.
