Defending Guinness PRO14 champions Leinster appear to be the front runners after finishing the regular season unbeaten, but provincial rivals Munster will be determined to spoil their parade at the Aviva Stadium. GUINNESS PRO14 SEMI-FINAL: Friday, September 4 LEINSTER (1st, Con A) v MUNSTER (2nd, Con B), Aviva Stadium, 7.35pm (live eir Sport 1/eir Sport Facebook/Premier Sports 1/SuperSport 1DAZN/www.pro14.tv/deferred TG4) Team News: Leinster head coach Leo Cullen has made a dozen personnel changes to the team to play Munster in tonight's hotly-anticipated semi-final clash at IRFU HQ. Hugo Keenan, Devin Toner and Will Connors are the only players retained from the side that secured a 28-10 win over Ulster, as Cullen brings back in 12 players who started the previous week's 27-25 success against the Munstermen. Captain Jonathan Sexton and Luke McGrath are at the helm of a back-line that includes Keenan, James Lowe and returning full-back Jordan Larmour in the back-three, with Garry Ringrose, a try scorer in last month's first game, and Robbie Henshaw in the centre. Winning his 247th Leinster cap, Toner combines with fellow international Scott Fardy in the second row, supporting a front row trio of Cian Healy, also a member of the province's 200-cap club, Ronan Kelleher and Andrew Porter. The hard-tackling Connors has edged out Josh van der Flier for the openside flanker role, with Caelan Doris also eager to make his mark at blindside and Jack Conan packing down in the number 8 position. Meanwhile, Munster boss Johann van Graan has brought Stephen Archer, Billy Holland and Jack O'Donoghue back into the pack for their second showdown with Leinster in the space of 13 days. The Conference B runners-up will field an unchanged back-line for the third week running, with Shane Daly retaining the number 15 jersey alongside the in-form Andrew Conway and Keith Earls, who made his 100th PRO14 appearance last Sunday. Chris Farrell and Springbok star Damian de Allende team up in midfield for the third successive time, while JJ Hanrahan, fresh from winning the PRO14 Golden Boot award, lines up outside Conor Murray at half-back. Archer rejoins Jeremy Loughman and Niall Scannell in the front row and Holland pairs up with Tadhg Beirne, last week's man-of-the-match, in the engine room as Fineen Wycherley drops back to the bench. There is a first start for Waterford native O'Donoghue since rugby's return as he swaps places with Chris Cloete in the back row, while versatile back Mike Haley, who recently recovered from a calf injury, is in line for his first appearance since the season's restart.

We've had some tough ones this season. I literally looked back over some of the fixtures yesterday - 3-0 away to Zebre, that was a tough one! But the players know each other so well. There's always a huge challenge in that itself. "Over the last number of seasons listening to various different Munster players being interviewed, particularly some of the guys who have been around a while like Peter O'Mahony, Conor Murray, Keith Earls and Billy Holland, and their desperation for silverware. So, I’ve heard what it means to them. "It clearly does mean a lot to them. We know we're going to be coming up against a team that is very highly motivated, as you'd expect at a semi-final stage.So we need to understand what we're going to be coming up against. "But it's also making sure we focus on ourselves so we deliver a really good Leinster performance as well, because that's ultimately what we’re in control of. Where will it rank? We'll wait and see. But certainly we're expecting it to be right up there, for sure."

Graham Rowntree (Munster) -

I'm happy with where we are mentally and physically at the moment going into this game. We've played against them enough and previous form means nothing to me for this team. It means nothing.

"All I'm really stressing to the guys is how hardened we are going into this game given we've not played rugby for a long time. Very quickly we're battle and match-ready going into a huge game.

"We have got so much to go for. That's our energy and belief going into this game. Why not us? There is no reason why we can't win Friday night. We've got to be better across the board against the current champions.

"We've had two games now to get used to what's going on in the breakdown, so I expect us to be better there, more clinical there, and not shell as many penalties as we did last Sunday at the breakdown. So there's a whole set of areas for us to be better at but I'm confident that we're going in the right way.

"We’ve had a good few weeks and I think you are seeing that, particularly with Steve (Larkham's) involvement with the group, how we are trying to challenge teams with our attack. You are certainly seeing things he's working on with the group. It's been good but we'll see Friday night how good we are."
