'Completely different set-up'published at 14:57 British Summer Time 19 September 2020
Paul Grayson
Former England fly-half on BBC Radio 5 Live Sports ExtraThis game has almost got derby status with the encounters they have had. In last year's final, Saracens had a squad capable of grabbing the European Cup by the scruff of the neck and totally dominating.
It’s a completely different set-up today with the squad they have got.

Owen Farrell is serving a five-match ban for wiping out Wasps' Charlie Atkinson with a eyesore of a high tackle.

Image source, Getty ImagesSaracens may held onto more of their stars than many thought when their relegation to the Championships was announced, but they are still light of six starters from these teams' meeting in last season's final.
Liam Williams is back at Scarlets, Alex Lozowski is on loan at Montpellier where prop Titi Lamositele has ended up on a permanent deal, Ben Spencer has gone to Bath, George Kruis is en route to Japan and Will Skelton is at La Rochelle.
It is perhaps the bench where you feel the stress of Saracens' situation most keenly...
Where in 2019 they were calling on Nick Isiekwe, they have Callum Hunter-Hill covering second row. Richard Wigglesworth was the scrum-half sub, today it is some-time Wales nine Aled Davies. Schalk Burger, Nick Tompkins and David Strettle brought experience and guile that it is harder to see in Calum Clark, Manu Vunipola and Dom Morris.

Full-back Alex Goode moves to fly-half to fill in for the banned Owen Farrell.
England back Elliot Daly takes over at full-back in place of Goode with Alex Lewington and Scotland's Sean Maitland completing the back three.
Saracens:Daly; Lewington, Taylor, Barritt (capt), Maitland; Goode, Wigglesworth; M Vunipola, George, Koch; Itoje, Swinson; Rhodes, Wray, B Vunipola.

Sexton started last week's Pro14 final win over Ulster on the bench but is back in the starting line-up - as are scrum-half Luke McGrath, hooker Sean Cronin and flanker Will Connors.
Josh van der Flier is on the bench.
Leinster: Larmour; Keenan, Ringrose (capt), Henshaw, Lowe; Sexton (capt) McGrath; Healy, Cronin, Porter; Toner, Ryan; Doris, Connors, Conan.
Replacements: R Kelleher, E Byrne, Bent, Baird, Van der Flier, Gibson-Park, R Byrne, O'Loughlin.
25 straight wins and counting...published at 14:37 British Summer Time 19 September 2020
Image source, Getty ImagesSince Leinster lost to Saracens in Newcastle in the final of last season's competition on 11 May, they have racked up 25 straight victories.
Last weekend, they rested key players and still had enought to win their third straight Pro14 title. They are top seeds in the quarter-finals after sweeping through the pool stages with six victories out of six. And the all-knowing bookies make them hot favourites to go one better than they did last year.
Going down with a final fight?published at 14:32 British Summer Time 19 September 2020
Image source, Getty ImagesIs this really an era-ending season for Saracens? The death of a dynasty?
Winners of three of the last four Champions Cups, champions in four of the last five domestic campaigns, they will win neither next season.
Financial sleigh-of-hand has been punished with relegation to the Championship and no European rugby for at least two years.
This tournament is their only chance to crown ther period of unprecedented dominance with another pot on the pile.
If they are to snatch silverware on their way through the trapdoor, this might be the biggest obstacle they have to overcome...
