Champion Cup: What if it is tied in the Final?
Should the scores be tied at the end of full time then 20 minute (two periods of 10 minutes) of extra time will be played.
If at the end of extra time the scores are still level, then the winners will be the team which has scored the most tries in the game, including extra time.
If the teams are level on points and tries at the end of extra time then the winners will be determined through a place-kicking competition.
In the case of the penalty shoot-out each team will be asked to nominate three goal-kickers.
The kickers need not be predetermined, but they must come from the players on the pitch at the final whistle. No substituted or dismissed player will be permitted to take part. The end at which the competition takes place will be determined by the toss of a coin. The team to kick first will also be determined by the toss of a coin.
Each kicker will have two kicks from designated positions on the 22 and 10 metre lines and after each team has completed their six kicks a winner will be declared.
If the teams remain deadlocked the competition will continue on a sudden-death basis.
* Saturday's final at the Grand Stade de Lyon is on course for a 59,000 sell-out attendance.
One thing is certain come the final whistle, there will be a new name on the trophy as both Racing 92 and Saracens have yet to experience European Cup glory.
Racing are the ninth Top 14 club to reach the Final along with Toulouse, Brive, Colomiers, Stade Francais Paris, Perpignan, Biarritz Olympique, RC Toulon and ASM Clermont Auvergne.
Saracens, who have won eight matches out of eight in the current campaign, will be appearing in the Final for a second time. In 2014, they were defeated 23-6 by RC Toulon.
Since the tournament went to home and away fixtures in 1997/98, no club has won the title with a 100 percent record from the nine games.
The 2012 champions, Leinster, were unbeaten, but they drew their opening match against Montpellier.
Racing will be bidding to make it four titles in a row for Top 14 clubs – following Toulon's historic hat-trick.
Following his successes with Toulon in 2013 and 2015, Racing's Chris Masoe, who will be 37 the day after the final, is in line to join an elite group of players who have won the title with different clubs.
The five 'double' winners to date are: Philippe Carbonneau (Toulouse and Brive), Cédric Heymans (Brive and Toulouse), Federico Mendez (Bath and Northampton Saints), Frederic Michalak (Toulouse and Toulon) and Eoin Reddan (Wasps and Leinster).
Ahead of the Final, Racing's Wales second row, Luke Charteris, leads the tournament tackling stats with 107.
Mako and Billy Vunipola are in line to become the eighth set of brothers to win the title after Olivier and Philippe Carbonneau (Toulouse), Bryn and Jan Cunningham (Ulster), Martin and Will Johnson (Leicester), Isitolo and Finau Maka (Toulouse), Denis and John Fogarty (Munster / Leinster), Rob and Dave Kearney (Leinster).
Three of the Racing coaching staff have had experience of a European Cup Final.
Laurent Travers lifted the trophy with Brive in 1997, Laurent Labit was the losing No.10 for Colomiers against Ulster in 1999, and assistant coach, Ronan O'Gara, is as a two-time winner with Munster.
Owen Farrell of Saracens is the tournament's top points scorer with 106.
Wenceslas Lauret will be looking for a better outcome on Saturday than six years ago.
The Racing flank was a losing finalist with Biarritz Olympique in 2010.
Saracens will be bidding to become the first Premiership club to win the trophy since Wasps in 2007.
Of the five previous Anglo-French finals, Premiership clubs lead the way with three wins to the Top 14 outfits' two.
Joe Rokocoko (Blues 2003), Dan Carter (Crusaders 2002, ‘05, '06, '08) and Ben Tameifuna (Chiefs 2012, '13), are looking to complete the coveted double of Super Rugby and Champions Cup titles.
