Karl Pratt faces his former club in the crunch showdown with Leeds on Sunday and has boldly declared: "I want to show them what they are missing."

The 23-year-old left Leeds in acrimonious circumstances following a fall-out with Rhinos coach Daryl Powell, joining the Bulls at the beginning of the season.

"The way I left Leeds was a bit sour because I left for personal and not professional reasons," said Pratt. "But after speaking to Brian Noble last year, I always wanted to come here.

"Brian has brought me on as a player and after some of my recent performances, I'd like to think that Leeds would be wishing that I was still there. I will still improve further and hopefully, in the future, they will really regret letting me go.

"But to be honest, being pushed out by Leeds was a blessing in disguise because it made it a little bit easier for me to come to here and now I can just concentrate on doing well for Bradford."

Ahead of Sunday's game, where victory for the Bulls will clinch the Minor Premiership title, Noble warned: "Karl brings a lot of enthusiasm to the team and will be looking to make an impact against Leeds - as long as he doesn't get over-involved."

The talented utility player - who will undergo an operation on a damaged shoulder capsule at the end of the season - he has blossomed under Noble's guidance, and following his stunning performance at London last week, which inspired the Bulls to a 54-12 victory, Pratt is ready to do it all over again on Sunday.

He added: "If I start against Leeds then hopefully I can continue where I left off last weekend. If I am playing stand off, on the wing, or coming on from the bench, then I have to make sure that I have a positive influence."

With influential trio Leon Pryce (sternum), Lesley Vainikolo (hamstring) and Stuart Fielden (knee) all set to be ruled out, extra responsibility will fall on the shoulders of former Rhino Pratt.

Noble, meanwhile, has added youngsters Richard Moore, Chris Bridge, Aaron Smith and Karl Pryce to the squad.

The Bulls boss will check on the fitness of his players during training today but will not name his side until tomorrow.
