Here, we look back at the five most recent instances of clubs winning European and domestic titles in the same season.

RC Toulon – 2014

This was the second of Toulon’s three successive European titles. They defeated Leinster Rugby and Munster Rugby, before beating Saracens 23-6 in the Cardiff final. Their domestic featured a kicking masterclass from Jonny Wilkinson, who scored 12 points as they defeated Castres Olympique 18-10 at the Stade de France.

Saracens – 2016

Saracens’ dominance in England and Europe came to fruition in 2016, when they saw off Northampton Saints and Wasps, before Owen Farrell kicked all 21 points in their 21-9 final win over Racing 92 in Lyon. Farrell then kicked 13 points in the domestic final, where Sarries beat Exeter Chiefs 28-20 at Twickenham.

Leinster Rugby – 2018

Leinster got their fourth European star in 2018, dominating knockout matches against Saracens and Scarlets before a nervy 15-12 win over Racing 92 in the final in Bilbao. Their double was sealed by a thrilling 40-32 PRO14 defeat of Scarlets at the Aviva Stadium.

Saracens – 2019

There was another double for Saracens in 2019, when they notched impressive wins over Glasgow Warriors, Munster Rugby and Leinster Rugby, who succumbed 20-10 in the final at St. James’ Park in Newcastle. As in 2016, their domestic final was very dramatic, as they edged out Exeter Chiefs 37-34 at Twickenham.

Exeter Chiefs – 2020

The Devon-based club finally got their hands on the Heineken Champions Cup and the Gallagher Premiership trophies last year. They denied Racing 92 in the European showpiece, winning 31-27 at Ashton Gate, before proving too strong for Wasps, securing a 19-13 victory at English rugby’s HQ.

Toulouse’s TOP 14 final victory over La Rochelle last week - a repeat of the Heineken Champions Cup decider – meant that the five-time European champions became the latest team to complete a European and domestic double.
