Then there is Cardiff Blues. They lie in fifth just four points adrift of Leinster but with a game in hand although a trip to the Sportsground on Friday night could soften their cough as Eric Elwood's side chase their best Magners finish to date.
Dealing with the more than likely however, Ulster supporters looking for some sort of recompense at the RDS for the disappointment of Heineken exit won't find it in D4. Expect Leinster to rest a few stars, though not many and register their 20th win of the League.
And with just Aironi (away) and Warriors at the RDS to follow, Leinster look set for a home semi final.
