On five occasions Leeds Rhinos and St Helens have collided at Old Trafford to determine the destination of the Super League title.
In three Grand Finals in a row from 2007-09, the Rhinos ended St Helens’ unbeaten record in Grand Finals with three title wins in a row.
Then in 2011 they beat the Saints to become the first side to win the Grand Final from fifth.
The Saints avenged those defeats last year as they made it four titles in a row by defeating Leeds 24-12.
Leeds gained a measure of revenge earlier this season with a Blake Austin drop goal defeating the World Champions in their own backyard and now the two will collide yet again tonight at Headingley.
Ahead of this, Barrie McDermott has warned that the inconsistent Saints will come good.
He warned Super League clubs: “Saints, I am sure of it, will come good. They don’t have to be great all season. They just have to make the play-offs and be great then.”
Earlier on Sky Sports, Brian Carney said: “If I am a team in front of St Helens I am worried.
“Coaches are story tellers and Paul Wellens has a great story to tell his players.
“They have never won a title from being seventh in May.”
Tonight they start against Leeds Rhinos.
