Leinster's strength in depth is "crazy" but Munster could still catch the European champions out this afternoon, according to Tomas O'Leary.
The sides meet at the RDS (3.15pm) in the Guinness Pro14 semi-final, just a week after the Blues won the Champions Cup.
Leo Cullen will be without Robbie Henshaw, Johnny Sexton and Rob Kearney following their exertions against Racing 92 in Bilbao.
However, that just means that the Blues hand starts to Ross Byrne and Jordan Larmour, who were in place when Leinster beat Munster in Limerick earlier this season.
Joey Carbery is also named to start.
"It’s a great chance for Munster to catch them but this Leinster side is full of confidence and the strength in depth that they have is crazy," the former Munster and Ireland scrum-half told RTÉ Sport.
"Munster probably feel they should have got to a European final and watching Leinster win their fourth European Cup would have been very difficult to stomach.
"I’m going to go with Leinster based on their form all year and the strength in depth of the squad. Hopefully Munster might catch them."
It was reported during the week that, for various reasons, Munster returned 900 tickets from their allocation although the game is now expected to be sold out.
O'Leary acknowledged that the rivalry has lost some of its edge in recent years.
"Looking in from the outside you could argue that [it's not as intense]," he said. "Leinster are at the height of their powers now.
"Leo Cullen was very smart when he brought his Leinster team down to Thomond Park earlier in the year.
"He didn’t bring his first team yet they won so I think he’s probably going to do the same, albeit some of the changes will be enforced this time.
"Of course, the two teams will go out to win and put their stamp on it but I don’t think the rivalry is as big and it’s not capturing the imagination of the public as much as it used to."
