Both teams scored thrilling semi-final victories last week, with an extra-time drop goal from Luke Gale putting the Tigers into the final before Leeds edged out Hull by two points on Friday night to reach a record-equalling 10th Old Trafford showpiece.
The Rhinos have a magnificent Grand Final record, winning 7 of their previous 9 including each of their last six, but they will be up against the team of the season, whose spirit was encapsulated by Gale’s remarkable semi-final performance.
The England half-back, one of three nominees for the Man of Steel award, enhanced his reputation further with a perfect kicking display, less than three weeks after undergoing surgery to remove his appendix.
Castleford finished 10 points clear of Leeds in the regular season and have beaten them four times this season, including a 66-10 success at The Jungle back in March and a 38-24 victory in the Super 8s a month ago.
Leeds are best price 7/4 with Betfred to buck the trend with victory in Manchester.
