(5). Ulster have won the coin toss to determine the 'home' side on the day. They will use the home 'England' dressing room at RFU headquarters.
(6). The all-Irish final means Ireland will have an additional place in the 2012/13 Heineken Cup tournament, with Connacht joining Leinster, Munster and Ulster in the competition for the second successive season.
(7). Twickenham has hosted three Heineken Cup finals before, with English sides winning all three. Northampton Saints beat Munster in 2000, London Wasps overcame Toulouse in 2004 and Wasps were victorious again in 2007 against Leicester Tigers.
(8). The game is already an 82,000 sell-out.
(9). Bookmakers make Leinster favourites at 3/10, with Ulster currently priced at 3/1.
