"Leinster vs La Rochelle... again" - Top 5 Champions Cup matches to watch this weekend

Qualification hopes, home advantage and survival are all on the line. Here are the five standout fixtures that will shape the third round.

Two of only three teams still boasting a perfect 10-point record, this is a mouth-watering contest before you even factor in the history. It is a repeat of last season’s final in Cardiff, where Union Bordeaux-Bègles edged Saints 28–20 in a match packed with drama.

That victory delivered UBB their first European star and produced some of the most talked-about celebrations in recent memory. Bordeaux’s post-match antics – including a pointed imitation of Henry Pollock’s trademark try celebration – ensured the rivalry did not end at the final whistle.

With both sides flying in this year’s competition, this rematch feels primed for fireworks.

Ronan O’Gara against Leinster, again. It is a storyline that never seems to lose its edge. This fixture revisits not one but two recent Champions Cup finals: La Rochelle’s 24–21 win in 2022 and their dramatic 27–26 victory in 2023 at the Aviva Stadium.

Since 2020, the sides have met five times in the competition. The French outfit have won three of those encounters, including both finals, while Leinster’s only success came in the 2021 quarter-final. Across those five games, La Rochelle have outscored Leinster by just eight points (118–110).

Whenever these two sides meet, it feels like a proper European clash between two heavyweights.

A “battle of the Sharks” in name, though the two teams arrive on contrasting trajectories.

Sale have steadied themselves in Europe after dismantling Clermont, bouncing back from their opening defeat to Glasgow, even if domestic frustration followed against Bristol.

The Durban-based Sharks, by contrast, are still searching for momentum. Heavy defeats in both Champions Cup outings and a narrow URC loss to the Lions leave them under pressure. Off the field, there has been added intrigue.

Owner Marco Masotti has once again aired his frustration at Sale sharing the Sharks name, reigniting a branding dispute that only emerged once the South African side joined the URC and European competition. His tongue-in-cheek social media suggestion that Sale should become the “Sale Tuna” only added fuel to the fire.

The weekend closes with a heavyweight collision. Saracens and Toulouse sit level in the pool with one win apiece, each also licking wounds from recent domestic setbacks.

Toulouse thrashed the Sharks 56–19 at home before falling to Glasgow at Scotstoun, while Saracens have similarly split their results. Beyond the standings, this fixture carries a personal edge: Jack Willis versus his brother Tom. Both are relentless carriers, ferocious at the breakdown, and central to their packs’ identity.

It also provides an opportunity for the hosts to get themselves back on track after an inconsistent start to the season, which has seen them unable to match the expectations bestowed on them ahead of the campaign. If Mark McCall's side turn up and get a result against Toulouse, it would send a statement to the Prem, and to Europe.

Munster travel to the Stade Mayol under pressure, looking to reignite their campaign after successive inter-provincial defeats to Leinster and Ulster. The loss in Belfast in particular has left scars, and Toulon is never a forgiving destination.

Yet this is a meeting steeped in European tradition – a clash of two giants that evokes the old Heineken Cup nights when every game felt monumental. Munster know what is required here: two years ago they revived their Champions Cup campaign in this very stadium, fighting back from 10–0 down to secure a famous bonus-point victory.
