The province lost last year's final after losing an URC semi final.
World player of the year Josh van der Flier is hoping the home crowd in Dublin can act as a 16th man for Leinster in Saturday's Champions Cup final against La Rochelle.
The decider is a repeat of last year's final which was won narrowly by Ronan O'Gara's men.
The Blues suffered a surprise defeat at the hands of Munster at the Aviva Stadium last time out in the URC semi-final.
Leinster haven't won the Champions Cup for five years and van der Flier knows the importance of strong support:
The province's outgoing senior coach Stuart Lancaster says the players need to forget about the Munster defeat as they prepare for Saturday's Heineken Champions Cup final against La Rochelle.
And Lancaster says complete focus is required for the game at the Aviva Stadium as Leinster bid to win the trophy for the first time since 2018:
