What is the defining moment in the history of the Heineken European Champions Cup?
It's 25 years since the first tournament took place, in which time it has grown into one of the centrepieces of the Irish sporting calendar.
It has produced no end of iconic moments, from Ulster's triumph at Lansdowne Road, to Munster's breakthrough in Cardiff, and Leinster's first in Edinburgh.
There have been plenty of memorable moments outside of finals, including Munster's miracle match, ROG's drop goal, BOD's try, and Connacht's arrival to the big-time.
There have been controversies, too, from the Hand of Back to Bloodgate, bizarre finishes, and emotional moments - who, for example, can forget Munster's game against Glasgow after the passing of Anthony Foley.
And then, there's the contribution of the best of England and France, in particular, through the likes of Toulouse, Saracens, Toulon, and Clermont's nearly men.
Now, you can have your say on the most enduring moment.
