Speaking ahead of the game, he said: "We are confident, keen and motivated following our performance against Scarlets at Ravenhill on Friday night, but we are under no illusion that Llanelli, as a club and community, enjoy a great rugby tradition.
"Just because they have moved stadium I don't expect that the tradition will change, I firmly believe we will have to be playing at our best to come away with the points.
"If we hadn't won on Friday night all the hard work and victories in the last number of games would have been for nothing.
"We wouldn't have been back to square one, but it would have dented our confidence and that is not what this side needs."
Schifcofske returns from injury and Wallace is included in the squad following his last-minute withdrawal for the Ravenhill clash.
Cillian Willis is ruled out of the fixture. The young scrum half fractured his cheek bone during a training session on Monday. Carlo Del Fava and Timoci Nagusa are also unavailable due to injury.
