Leinster managed to cling to their lead and survive a late surge from Toulon, clinching a 29-25 victory at Dublin's Aviva Stadium that propels them into this season's Champions Cup final. The Irish side, who have endured defeat in their previous four European Cup finals, will now meet either the defending champions Bordeaux-Begles or the Premiership title‑holders Bath in the showdown scheduled for May 23. The match was anything but straightforward.

Early in the second half Leinster found themselves reduced to fourteen men after two players were sent to the sin bin, while Toulon mounted a thrilling comeback in the closing stages. Despite the pressure, the home side held firm and secured the win. In the opening half, Leinster’s forwards made a strong impression.

Flankers Jack Conan and Josh van der Flier each crossed the try line, giving the hosts an early advantage. Centre Garry Ringrose added another try, and captain Caelan Doris also found the back of the net. Fly‑half Harry Byrne contributed with a penalty kick and three successful conversions, rounding out a solid first‑half performance. Toulon, however, stayed within touching distance.

At the half‑time break they trailed by just three points, and the French club responded with two late‑stage tries that reignited the contest. Their points came from Seta Tuicuvu, Baptiste Serin and Gael Drean, complemented by two penalties and two conversions from Melvyn Jaminet.

The game’s early moments were marked by missed opportunities. Both Byrne and Jaminet failed to convert early penalty chances, the latter striking from just inside his own half.

Leinster soon found a rhythm after a series of attacking phases, and a powerful run by Conan resulted in a try that Byrne promptly converted. Leinster’s momentum was briefly halted when centre Robbie Henshaw suffered a serious head knock while attempting a tackle. The injury forced a six‑minute stoppage while medical staff attended to him, after which he was stretchered off the field, representing a significant blow to the team’s backline. Jaminet then found his range, slotting a penalty to narrow the gap.

Leinster continued to press, only to be denied a second try when scrum‑half Jamison Gibson‑Park’s effort was ruled out after a knock‑on in the build‑up. A second Jaminet penalty pushed the score to 7‑6 in Toulon's favour, but Leinster remained patient. Their perseverance paid off eight minutes before the break when Van der Flier collected a pass from Doris and dived over for a well‑executed try.

Byrne added the conversion, extending Leinster’s lead. Toulon still posed a threat, especially after Leinster prop Andrew Porter received a yellow card for a head‑to‑head clash with Toulon number eight Mikheil Shioshvili. Toulon answered quickly, with Tuicuvu diving over for an opening try. The game’s disciplinary drama continued when referee Luke Pearce issued a second yellow card, this time to Byrne, leaving Leinster with two players in the sin bin as the teams headed into the interval with a narrow 14‑11 lead for the Irish side.

The numerical disadvantage lasted only five minutes in the second half before Toulon’s hooker Teddy Baubigny was also shown yellow for a head‑contact incident with Van der Flier. Leinster seized the moment, launching an aggressive attack that saw Ringrose exploit the space created and score the team’s third try.

Byrne’s accurate penalty kick further stretched the lead, and with thirteen minutes remaining, Doris capped a sustained period of pressure with his own try, which Byrne again converted. Toulon’s substitute scrum‑half Baptiste Serin offered a brief resurgence, scoring a try in the 70th minute that Jaminet converted, followed by a late try from Gael Drean that added a few more points.

Despite Toulon’s late heroics, Leinster’s disciplined defence and efficient scoring had built a sufficient cushion. The final whistle confirmed a 29‑25 win, sending Leinster to their ninth Champions Cup final in the competition’s history. The victory not only ends a series of final‑stage disappointments but also sets up an exciting climax to the tournament, with the Irish province eager to finally lift the coveted trophy after years of near‑misses. Leinster’s campaign has been characterized by resilient defence, opportunistic attacking play, and the ability to withstand adversity, as demonstrated by their handling of injuries, sin‑bin periods, and relentless French opposition.

Their blend of experienced leaders like Doris and emerging talents such as Van der Flier has created a balanced squad capable of adapting to the high‑stakes environment of European rugby. As they prepare for the final, the team will look to build on the lessons learned from this hard‑fought semi‑final, focusing on maintaining composure under pressure, executing set‑piece strategies, and capitalising on scoring opportunities. The upcoming final against either Bordeaux-Begles or Bath promises a clash of contrasting styles: the French side’s flair and physicality versus the English club’s structured, forward‑driven approach.

Leinster will need to leverage their depth, tactical versatility, and the leadership of captain Caelan Doris to navigate the final’s challenges. If they can replicate the determination shown against Toulon—overcoming injuries, managing disciplinary setbacks, and delivering in clutch moments—they stand a strong chance of finally breaking their recent finals drought and securing the Champions Cup title.
