The Broncos ran in 13 tries as they dominated from start to finish, ruthlessly exposing their part-time opponents.

Now, having failed to progress past the fifth round since 2007, Powell is looking to engineer a trip to Wembley.

"It has been a long time since this club had a good cup run," he said. "With the Challenge Cup you get a couple of wins and suddenly you are in the semi-finals.

"We had nine Londoners out there today and they know what a good run would mean to the club.

"It is exciting for the players and exciting for the fans and we want to build on this result."

Jowitt hails effort

Dewsbury coach Warren Jowitt, who made eight changes for the clash, admitted the contest had simply been a bridge too far for his troops.

"We have to be realistic and it was always going to be difficult for us to come here and get a result," he stated.

"We are not a Featherstone or a side like that, somebody who can steal a result against a Super League team.

"We had a young side out there today and I thought we had a good crack.

"The league is obviously the more important competition for us and hopefully scoring a try near the end will give us that bit of confidence to take forward."
