Rhinos star Jamie Peacock thinks his old team mates at Bradford Bulls could cause a shock tonight in their Grand Final Eliminaton game. The Bulls, having finished fifth, travel to Widnes' Stobart Stadium to face Wigan. The Warriors, having battled to finish fourth and gain home advantage, have been forced to switch the game to Widnes after the JJB Stadium authorities refused them permission to play at home because Wigan Athletic are also at home this weekend. Peacock believes that uncertainty will have little effect on the game but that revenge might be enough to get the Bulls through. He commented, "Wigan against Bradford is a difficult one to call. I think there at benefits and disadvantages to playing the game at Widnes and I think they will cancel each other out so it is just down to the team who wants to win it more. Wigan have got three of four world class players and I don't think the Bulls have that in the current squad. However, they are well coached and they will want to put right what happened last year in the play offs against Wigan. Being an ex-Bradford player I would like to see them go through. "In the other game I think that Warrington are going to struggle in Perpignan. They have got five players out already and most of their front row and you will struggle out there against the big blokes from the Dragons. Pottsy has been building for the play offs for a couple of weeks now, resting players and getting ready for this game so I think it will be Bradford and Catalans going through," added Peacock.
