With just six days to go before Leeds Rhinos' visit to Valley Parade, Paul Deacon isn't worried that Bradford Bulls are not in peak form.

Speaking in the wake of their home win over Castleford last night, the scrum half said: "At the moment our problem seems to be that we can't perform for the full 80 minutes.

"We have lapses in concentration near the end of a match, but it is probably a good thing that we are not hitting our peak yet ahead of the play-offs. We won

40-18 last night and weren't at our best."

The Bulls were a shade lucky to be 12-0 ahead at half-time, but then roared home against the Tigers with five tries in 20 minutes in the second half.

Deacon, whose six goals made him the first past the 100-goal mark in Super League this season, added: "We played some decent rugby at times, and it was good preparation for the Leeds game because we took a step up from the match against Hull last weekend.

"Yes, we made a few too many errors in the first half last night, but we played some decent stuff.

"We'll look at the positives, learn from what we did wrong, and hopefully we'll improve next week and stuff Leeds!"

The Great Britain international added ominously: "Perfection doesn't happen overnight, but I can't wait for us to click into gear because we will blow somebody away."

The Rhinos have beaten the Bulls twice this season - 17-4 in the Challenge Cup at Valley Parade in February and 28-20 in the Super League at Headingley in May

The Bulls' only injury worry from last night was second-rower Daniel Gartner, who got a bang on the hip and was replaced by Lee Radford in the 48th minute.
