Pau v Leicester (13:00 BST)
A reminder that a moment's silence will be observed at all the opening round's fixtures.
This comes after former Sale second row Hyron Andrews died on Friday at his Johannesburg Lions' team hotel before their Champions Cup match at La Rochelle.
Pau v Leicester (13:00 BST)
Try-scoring bonus points in this season's Champions Cup pool stage will be awarded only to teams who cross at least three more times than their opponents - rather than for simply scoring four or more tries.
It has been felt that losing teams could pick up a four-try bonus point too easily as opponents with a comfortable lead ease off in the final quarter.
There will also be a change in qualification criteria for the last-16 stage.
Previously the top four teams from each of the four six-strong pools would progress, with home advantage in the knockouts decided by a seeding based on group-stage records.
Only three teams from each of the four pools will now go through automatically, with the remaining four last-16 spots allocated on the basis of table points collected.
Pau v Leicester (13:00 BST)
Pau, who played in the Champions Cup for the first time in 25 years last season, have won five of their six Top 14 games this season.
They are second, behind Toulouse.
On paper, are they tournament dark horses?
Pau v Leicester (13:00 BST)
Two-time European Cup winners Leicester Tigers last won the tournament in 2002.
Can they get back to being the best of the best?
