The Canterbury-Bankstown Bulldogs and Sydney Roosters are two of the three oldest clubs currently playing in the NRL and this week will meet for the 15th time in finals.
The Roosters are a 1908 foundation club with, while the Bulldogs entered the competition in 1935 and have eight premierships next to their name.
The rivalry between the two clubs can be traced back to the 1980 grand final when the Roosters, who were the glamour club of the 1970s, handed over the mantle to the "Entertainers" of Canterbury.
The 1980 grand final victory saw the beginning of a golden age for the Bulldogs, winning again in 1984, 1985 and 1988.
The Roosters wouldn't lift the trophy again until 2002, the year the Bulldogs looked to be running away with the title, until the NRL stripped the Bulldogs of 37 competition points due to Salary Cap breaches, sending them from first to last on the competition and ending the season in 16th position.

The Bulldogs featured in the 2012 and 2014 Grand Finals as well as claiming the 2012 minor premiership, while the Roosters won the 2013 premiership and have been the minor premiers the last three seasons.
The Bulldogs and Roosters have met on two occasions this year with the Roosters claiming the points on both encounters, but finals is a different competition.
The Bulldogs and Roosters have met 14 times in finals, including Grand Finals and the Bulldogs have won eight of the 14 clashes.
