Scarlets head coach Wayne Pivac has acknowledged the degree of difficulty his team face in Saturdayâs Guinness PRO14 final.
The Welsh side, PRO12 champions last season, head to Dublin for a quick return appointment with European champions Leinster.
Scarlets were defeated 38-16 by Leinster in a European Champions Cup semi-fnal five weeks ago, before the Irish heavyweights went on to lift the trophy by beating Racing 92 earlier this month.
âThey are a very good side,â Pivac said. âWe only have to look back to our semi-final where we were completely outplayed.
âThey have gone on to win the big prize and be crowned European champions, and deservedly so.
âTo back that up against a good Munster team (in last Saturdayâs PRO14 semi-final) is not an easy task a week later after celebrations and euphoria of winning it, and was to me a testament to how strong that squad is.
âThey will be better this weekend with some guys freshened up.
âWe are expecting a massive game. Itâs a massive challenge for us, but I think itâs a great game â last yearâs PRO12 champions up against this yearâs European champions.
âIf you want to win it, you want to do so against the best.â
Wales centre Hadleigh Parkes makes his 100th Scarlets appearance, with full-back Leigh Halfpenny returning to action after missing last weekâs semi-final victory over Glasgow due to a hamstring injury.
Elsewhere, Johnny McNicholl moves to the wing and Tadhg Beirne lines up at Number 8 instead of an injured John Barclay, with Lewis Rawlins handed a second-row start alongside Steve Cummins.
Beirne, who will tour Australia with Ireland this summer, makes his final Scarlets appearance before joining Munster next season.
And Pivac added: âHe has played second-row, six and eight â he would even play on the wing if you wanted him to. He is a great team man, and is great off the field and works very hard at his game. He has been superb, I canât say enough about him.â
Fly-half Johnny Sexton has recovered from a groin injury to spearhead Leinsterâs title assault, but a knee injury sidelines centre Robbie Henshaw, with captain Isa Nacewa lining up in midfield for his final appearance before retirement.
