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.
Speaking to the local media this week, David Humphreys insisted that Gloucester are looking forward to kicking off the new European Rugby Challenge Cup against Brive on Thursday evening, although an unfamiliar opponent and a five day turnaround will pose a challenge.
Director of Rugby David Humphreys felt that his Gloucester side put themselves in a position to put Saracens under real pressure at Allianz Park on Saturday, praising his team's commitment and defence, while admitting that a lack of accuracy hit their chances in the second half.
Speaking to the local media at Allianz Park, Tom Savage was disappointed after the defeat at Saracens, but claimed Gloucester did plenty of good things and could've taken more than a losing bonus point.
In case you missed it, there was plenty of activity on the official Gloucester Rugby website following the 55-0 European Rugby Challenge Cup win over CA Brive, including a number of post match video interviews.
