Cardiff will open their Heineken Champions Cup campaign in a thrilling Saturday lunchtime meeting with defending champions, Stade Toulousain.
The Blue and Blacks will host the French giants in a repeat of the inaugural Heineken Cup final in Cardiff 25 years ago.
The mouth-watering encounter, which will be broadcasted live on Channel 4 and BT Sport, will be the latest in a long line of European encounters between the two iconic clubs.
The curtain raiser will be followed by a trip to Harlequins a week later in the second round of matches on the Road to Marseilles.
The reverse fixture against the English champions will be played under Friday Night Lights at Cardiff Arms Park on January 14 before the campaign comes to a close with a Saturday afternoon game in Toulouse against the five-times champions.
Tickets will be available for Cardiff’s Heineken Champions Cup fixtures later this month, and are included as part of the 2021/22 Season Membership packages.
