There's the Keith Earls versus the great man himself - and great to see Brian O'Driscoll back - then the Felix Jones and Rob Kearney contest at full-back and of course the Maestro and the Young Pretender, a contest that worth the entrance money alone.
And loads more.
Leinster are the form team, have lost just three games in the league, and despite protestations to the contrary from their own camp, they go into this game as favourites and as the side with the most to lose.
They are eight points clear but after today still have to go to Ravenhill and Rodney Parade, two places that will not give way points handy.
They also have a full strength squad to choose from whereas Munster are without key players in Paul O'Connell, Donnacha Ryan, Denis Hurley and Conor Murray never mind the likes of the long term injured, Doug Howlett, Denis Leamy and Niall Ronan.
Nevertheless they wont wont use that as an excuse and will believe that their best performance will be good enough to get something of this game.
