The Scarlets will be determined to avoid a Heineken Cup whitewash, after Leinster rediscovered their try-scoring touch to record a 33-14 triumph at the RDS.
The Irish side had only crossed the white wash on three occasions in their previous four pool games, but after crossing for five tries, the defending champions have kept their Heineken Cup campaign alive while the Scarlets remain rooted firmly to the bottom of the Pool 5 table.
“We owe each other and our fans a good performance at home,” McCusker said after another disappointing defeat in the competition.
“Our supporters have not had much to cheer about in the last few weeks so we want give them something to get excited about and end the competition on a high.”
Fly half Aled Thomas gave the Scarlets an early lead with a penalty in front of the posts after Devin Toner made a tackle but failed to roll away.
The Scarlets’ next visit to the Leinster 22 was rewarded with a Liam Williams drop goal but the home side were by then in the lead having kicked a penalty to touch and set up three phases of play that ended with the prop Cian Healy forcing his way over the line.
Flanker Shane Jennings scored Leinster’s second try after another driving lineout from a penalty and the wing Luke Fitzgerald claimed the third after Jonathan Sexton had been held up on the line.
The Scarlets finished the half in a positive mood after Thomas chipped to the line for Liam Williams to catch the ball unopposed and score.
Rob Kearney secured the bonus point after the break after Heaslip picked up from a scrum and passed inside to the full back.
Thomas’s second penalty brought the Scarlets to within 12 points of their hosts Ian Madigan completed the scoring with a try and drop-goal conversion.
