This is it: the culmination of the season and a final swansong for many of the Leinster family.
Tomorrow's match will be the final curtain call not only for Malcolm O'Kelly, Girvan Dempsey and Bernard Jackman -- stalwarts and legends all -- but also for other players such as Chris Keane and CJ van der Linde, who have all been a part of Leinster's success in recent years. In addition, we bid adieu to much of the coaching team as Michael Cheika and Chris Whitaker depart for Stade Francais, Alan Gaffney will focus solely on his Ireland commitments and Kurt McQuilkin returns to New Zealand.
With so much emotion riding on the occasion it is unthinkable that the end won't be the one deserved by these men. Nothing is a given, however and, as every rugby supporter knows well, sport can be cruel.
The Ospreys are a formidable side, littered with talent, and while Leinster remain unbeaten in the RDS in the Magners League this year they were one of the teams that came close to winning there.
The players are focused and will be giving it everything they have to ensure victory and it's up to the supporters to do the same. Home advantage is only as good as fans make it, and they must make the RDS as formidable a place as the opposition have experienced.
Every single blue-clad supporter must do everything in their power to get behind the boys tomorrow night. The increase in noise level when the team is defending as well as attacking is vital.
The atmosphere for the past few games this season has been electric. It's time to take it to the next level for the final.
Everyone is in this together. To use one of the team's mantras: Do All You Can Do.
