Castleford chief executive officer Steve Ferres insists the Super League club require 'significant' investment to make them a competitive force.
It has been a season of struggle for coach Ian Millward's side with the Tigers two points from the bottom of the table after winning just six of their 24 top-flight matches.
Castleford did not spend up to their maximum allowance on the salary cap and Ferres is working hard behind the scenes to introduce the changes required.
The club's CEO is also urging fans to sign up to their new membership scheme, stating without hitting their target of 5,000 members their chances of improving things on the pitch will be hindered.
Ferres hopes next season's acquisitions of Justin Carney, Michael Shenton, Lee Gilmour and Jake Webster will help bring about a change of fortunes
"I'm afraid there is no way of sugar-coating the current situation," he told the club's official website.
"The club needs to change on a number of fronts and also requires significant investment in order to re-establish Castleford Tigers as a competitive force in Super League. At a minimum we need to be in a position where we are capable of spending the full salary cap.
"I would like to reassure everyone that we are working very hard with a number of high quality business people to map out and introduce these changes but the fans are absolutely central to its future success.
"This year we will be introducing a new membership scheme in line with the 2012/13 season ticket which will offer a range of member benefits including discounts on official kit, offers from local businesses and more importantly, increased access to the board and players.
"It is a tall order but we ultimately need 5,000 members signed up for next season if we want to stand any chance of improving the club's performance both on and off the field, in the immediate term
"We know we have the loyal fans out there but we also know that they are becoming increasingly disillusioned as a result of the recent poor performances.
"This must change and with likes of new players such as Justin Carney, Michael Shenton, Lee Gilmour and Jake Webster, we expect them to bring a new vigour and enthusiasm to performances as well as professionalism to the club through their collective experience in the game.
"Fans must, however, be realistic - we are currently building a squad that will deliver competitive performances but without the necessary capital, we will continue to struggle to compete at the highest level.
"There are no quick fixes here but I want to implement a vision for the future which also puts investment in youth development and nurturing local talent at the centre of its ambitions - a community club that the Castleford community can be proud of."
