Starting from scratch, Williams is scheming to turn the Diesels into a Group Nine force with longevity but is adamant the transformation won't happen overnight.

Having recruited just one additional player (former Parramatta Toyota Cup star Toby Key) for this season, Williams yesterday revealed his plans to overhaul the Diesels.

"The idea is to pretty much start from scratch," he told The Daily Advertiser yesterday.

"The last club I was at was lucky enough to have good juniors, it was a top young squad but it took us two years to come good.

"The idea is to try and create a new culture and be competitive every round.

"It could take longer, who knows, but starting from scratch means everyone needs to be on the same page and working together that's the main goal.

"The results certainly aren't the main focus to start off with, it's about looking towards the back end of the season and helping the younger kids develop and hopefully making Junee a better club for the future."

Williams, who is expected to play lock or five-eighth this season, comes to the Diesels after leading Dubbo-Macquarie to the Group 11 premiership with the same technique last year.

Despite the loss of last year's captain-coach Damian Willis and enforcer Phil Latu, Williams believes the Diesels have the right mix of talent to threaten the competition with the addition of Key in the forward pack.

A big believer in a productive preseason, Williams said the Diesels would play the Group Nine and Group 10 combined competition, but would also play an additional trial game against Queanbeyan.

"We're going to Queanbeyan to play the Blues on the same weekend as the second week of the preseason competition.

"I just need to figure out how we'll do it, what team we'll play and see how we'll get around it.

"Our preseason is not results based at all, it's more to see what we're working with and what combinations we can come up with, who plays well outside of who.

"It's not about winning."
