Foley: It's all in our own hands
There could be a little bit of history created at the Aviva Stadium tomorrow evening as a Munster victory would make it the first season since the league started that the two biggest Irish rivals have won at each other's grounds.
Munster have won away to Leinster three times in the regulation season since the league started in 2001 and on each occasion have completed the double.
Leinster have done the double four times in this fixture and will make it five if they triumph tomorrow evening, having won 24-7 in Thomond Park at Christmas.
There has never been much between Leinster and Munster and as they head into their 29th league meeting the record stands at 16 wins to 13 for Leo Cullen's men.
Three of those ties have been at the knockout stage, with Leinster winning the only semi-final between them in 2010, while they each have one final success over the other.
Leinster won the 2002 final by 24-20, with Munster victorious on a 19-9 scoreline five years ago.
Munster have hosted 13 of the regulation league ties, winning eight and losing five.
Leinster have won nine of the dozen regular league clashes they hosted and there has never been a draw between them in the competition.
And with so much at stake, Munster coach Anthony Foley believes a lot of his men are coming good at the right time, with serious competition for places.
"I think a lot of fellas put up their hands you know. Behind the scenes a lot of work has been going on with a lot of players," he said.
"It's about creating depth, creating opportunities. Opportunities come from injuries and lack of form from others. Fellas have put their hands up."
Munster have their fate in their own hands heading into the business end of the campaign and Foley said they have everything to play for as they try to again make the knockout stages of the competition.
"We have four games left in the league; Leinster and Connacht away and then two at home against Edinburgh and Scarlets.
"They're four big games. It's a good place to be to have a relatively fit squad."
