Llanelli director of rugby Gareth Jenkins has warned his side that they must cut out the errors if they are to progress in Heineken Cup.
Last season the Scarlets were famed for their solid performances, and progressed to the semi-finals, only to be narrowly defeated by a last minute penalty from Leicester full-back Tim Stimpson.
But this season Llanelli's form has been inconsistent - and despite a 45-15 victory in round 1 over Glasgow, last Friday's 54-38 defeat to Bourgoin, means Llanelli need to put in a series of big performances in the remaining Pool matches to secure qualification to the final eight.
"I thought we played well against Bourgoin and were more than unlucky to lose the game," said Jenkins. "The difference between the two sides on the night was that we made too many errors.
Llanelli play Ulster in the Celtic League on Friday night- and Jenkins is all too aware that defeat will spell the end of their Celtic League campaign.
"It will be a huge disappointment not to reach the knockout stages of the competition," said Jenkins. "I think we've made enough progress this season to proceed further but we'll have to earn our victory.
"Ulster present us with a very different challenge to Bourgoin - the only similarity is that they are both very good sides and will both be tough matches.
"But, we're more than capable of going there and getting a win. We're a decent team and if we play to our full ability then we can get the result we want."
Llanelli resume their Heineken Cup campaign in round 3 against Sale Sharks on the weekend of December 6th.
