The fixtures are in for this season's European Rugby Champions Cup, which will see Toulouse kick off their title defence with a visit to Pool B opponents Cardiff on December 11.
The record five-time winners were crowned champions of Europe in May before going on to also beat French rivals La Rochelle to the Top 14 title one month later.
Toulouse won the inaugural Heineken Cup in 1996 after they defeated Cardiff in extra time in the Welsh capital, hoping the Arms Park will prove accommodating once more a quarter-of-a-century later.
That fixture will be televised on BT Sport, as well as on free-to-air television via Channel 4.
BT Sport will broadcast 'each of the 48 Heineken Champions Cup pool matches live' as the competition's main partner in the UK, while Channel 4 will air 'key fixtures in each round'.
Irish rugby legend Ronan O'Gara is looking to go one better leading La Rochelle in an elevated role this term, and they reignite their continental campaign in a Pool A clash with Glasgow Warriors.
Former employers Munster will also be in action on December 12 and face a tricky trip to Wasps, while last season's Pro14 winners and four-time European champions Leinster host Bath in Dublin.
Northampton Saints have the honour of hosting another French powerhouse, Finn Russell's Racing 92, in the tournament's opening fixture on Friday, December 10.
Will Toulouse become the first team in five years to successfully defend the Champions Cup? Let us know in the comments section.
Bristol Bears and Exeter Chiefs will also enjoy home comforts on the opening weekend after they were drawn opposite Scarlets and Montpellier for their first fixtures, respectively.
Premiership titleholders Harlequins will be among the last to begin their Champions Cup campaign when they visit Castres on December 12, the same day Sale Sharks are due to visit Welsh region Ospreys.
This is the second season in which the Champions Cup will operate on a two-pool format, with each team playing two first-round fixtures in an effort to reach the knockout stages.
The top eight teams from each group will advance to the round of 16—which is scheduled to get underway on April 8—with dreams of making the final at Marseille's Stade Velodrome on May 28.
English giants Saracens will be a notable absence for the second season in a row as they look to reacclimate to the Premiership following their 2020 relegation due to multiple salary cap breaches.
