Leinster

In an opening half that featured just one solitary try, the dominant theme was Leinster’s superiority in the scrum.

With former Leinster player Michael Ala’alatoa appearing to struggle on their tight-head side, Munster could not get to grips with their opposing front row, who were able to use the set-piece to relieve pressure time and time again.

Despite those difficulties, Munster still enjoyed plenty of territory but were lacking in accuracy when it came to the crunch.

Jack Crowley missed touch in what was a generally poor kicking display from those in red, while a Mike Haley knock-on after a poor Tom Farrell pass ended another attack.

Leinster struggled to convert their own opportunities but did take a 7-0 lead into the break thanks to Van der Flier’s early score.

After one of those initial scrum penalties, the visitors kicked to the corner with Ronan Kelleher finding Caelan Doris from the subsequent line-out.

While the maul made only marginal headway, there was to be no stopping Van der Flier when the back row peeled off the back and ran through the tackle of Craig Casey to score.

In what continued to be a low-scoring and disjointed game after the break, Harry Byrne and Crowley traded penalties a quarter of an hour after the restart.

Approaching the final quarter, Byrne added another three points with the boot but, as both sides turned to their benches, it felt a game already lacking in flow was becoming even more disjointed.

Replacement centre Dan Kelly’s try in the 70th minute set up an absorbing finish but, try as they might and despite plenty of late possession, Munster could not find a way through the Leinster defence for the telling score.

In truth, while the game did not lack intensity or ferocity, given the paucity of attacking quality on show, it was a fitting end to such a contest.

Both sides face another interprovincial derby in the URC next week with Munster travelling to Ulster on Friday and Leinster hosting Connacht the following day.

Australia prop Angus Bell will make his first Ulster start in Friday’s United Rugby Championship game against Leinster at Aviva Stadium (19:45 GMT).

Short-term signing Bell, who came off the bench in the Challenge Cup fixtures against Racing 92 and Cardiff, starts at loose-head with Ireland internationals Tom O’Toole and Tom Stewart completing the front row.

Centre Stuart McCloskey returns from the groin injury he sustained on Ireland duty last month. He is joined in midfield by Jude Postlethwaite, who missed last weekend’s defeat by Cardiff because of concussion.

Ulster head coach Richie Murphy has recalled several players after rotating his squad for the Cardiff game, with Nick Timoney and Juarno Augustus returning to the back row.

Jacob Stockdale is restored at full-back, while Rob Baloucoune – who has scored five tries this season – returns to the right wing. The first-choice half-back pairing of Nathan Doak and Jack Murphy are also recalled.

Ethan McIlroy is set for his first appearance since January from the bench after recovering from a knee injury.

Ireland forward James Ryan will earn his 100th Leinster cap in Friday’s interprovincial derby.

URC holders Leinster will be captained by Jack Conan, who came through graduated return to play protocols, with Caelan Doris not named in the squad.

Leinster head coach Leo Cullen has changed his front row after last weekend’s Investec Champions Cup win at Leicester, with Jack Boyle, Rabah Slimani and Gus McCarthy named to start.

New Zealand international Rieko Ioane will play his first URC game after a couple of Champions Cup appearances, while Sam Prendergast is restored at fly-half after Harry Byrne was preferred for the Leicester game.

Ulster have won four out of five URC games this season while Leinster have three wins and three defeats from six. Leinster won both meetings last season, including a comprehensive 41-17 win at Aviva Stadium in April.
