ADAM EUSTACE scored Gloucester's only try as Dean Ryan's side lost 19-7 against Llanelli.
Ludovic Mercier added the conversion but Ryan blamed a lack intensity for the defeat at Stradey Park.
"We have these pre-season games to highlight problems we don't want to encounter in the Premiership and in that respect it was very useful," Ryan said.
"But I was disappointed with the intensity levels we managed to bring to the game, particularly from our forward pack. We saw an improvement in the second half but by then it was too late.
"At times we also displayed a lack of creativity because we could have scored a number of times - but it was the lack of intensity that bothered me most.
"We need to make sure we create the right environment for the Premiership and that is what these games are for."
Ryan praised the contribution of prop Christian Califano as once again 'outstanding' and hopes next week to be able to welcome back Andy Hazell, Olly Morgan and Mike Tindall.
"I am sure when some of those guys are back in the squad our intensity levels will increase - that is what we are searching for and we want we need - it will be good to have these guys back involved," Ryan added.
Gloucester will await fitness reports to Haydn Thomas, Mefin Davies and James Simpson-Daniel following the defeat.
