Bernard Jackman and Wes Liddy join Daire O'Brien on the RTÉ Rugby Podcast to look back on a couple of classic clashes involving Irish rugby's two behemoths.
The Red Army battered the Blues 30-6 at Lansdowne Road in 2006 on their way to a first Heineken Cup at a time when the Celtic Tiger was still riding high.
Three years later, Leinster avenged the defeat that their fans still refer to as 'Black Sunday', with victory coming at a time when the economy was on its knees, the boom having turned to bust.
Jackman played in the 25-6 win at Croke Park and may well have figured in the first match, but for a broken leg.
Sit back and let the memories cocoon you.
