Chester FC chairman Simon Olorenshaw believes much more detail is needed about the potential financial impact of the Football League's controversial restructure plans.
Proposals released last week could see the Football League expand to four divisions of 20 teams below the Premier League, introducing a new fifth division between the National League and League Two.
Eight new clubs would need be added to the existing 92 and one idea is that there would be no relegation from League Two in 2018-19 with six additional teams being promoted for the National League.
While the prospect of a place in the Football League will appeal to non-league clubs, concerns have been raised over the revenue that would be lost through having less home fixtures and what would happen to the National League clubs not promoted.
BBC Sport contacted the 18 National League clubs who were not promoted or relegated last season to gauge opinion on the plans and the response was mixed.
Barrow AFC, Braintree Town, Southport and Torquay United were not in favour but Forest Green Rovers, Gateshead, Lincoln City, Macclesfield Town and Woking came out in support.
Most clubs - including Chester - said there was a need for more information before a decision could be made.
Olorenshaw responded: "Until it is clear how the change in the structure of the Football League will impact upon the ability to generate revenue, i.e. reduced number of home games, potential lack of FA Cup replay revenue, introduction of Premier League B teams, it is not possible to make a decision one way or the other."
Chester haven't been members of the Football League since 2009 when the club - then known as Chester City - was relegated at the end of the 2008-09 season.
The Blues began the 2009-10 campaign in what was then called the Conference Premier but off-field turmoil and deepening financial problems led to them being expelled in February 2010 and the club was wound up the following month at London's High Court.
Supporters organisation City Fans United formed phoenix club Chester FC and the Blues won three successive league titles, rising from the Evo-Stik League Division One North to the Conference Premier in three seasons.
Football League chief executive Shaun Harvey said the restructure plan was designed to alleviate fixture congestion by cutting down on midweek games and has the approval of both the Premier League and the Football Association.
"The Football League has recognised that fixture congestion is one of the major issues facing the professional game in this country," he said.
"We have seen a number of public spats this year in relation to scheduling and dealt privately with many others. The season only has a number of finite dates, and they are sought by all of us to try to get our games on at prime times."
But Brian Barwick, chairman of the National League, fears the proposals could be 'very damaging' to the competition.
He said: "The National League is very concerned about the potential consequences of any potential adoption of the Football League’s ‘Whole Game Solution Discussion Paper’.
"We strongly feel its attempt to re-shape the existing professional game structure has failed to take into consideration the effects of any change on football played below its proposed five divisions. We seriously believe it could be very damaging to the National League and its member clubs and will be determined to make that point very clear when we meet up with Football League officials to discuss their proposals.
"The National League is an ambitious and forward-thinking organisation as well as a well-established and well-loved competition and we will do everything possible to protect both its integrity and its commercial value."
Football League clubs will vote on the changes in June 2017. A 90 per cent approval rate, or 65 of the current 72 clubs, is required to get the go-ahead.
The key points of the new proposals:
- A five-division professional league of 20 teams each for the 2019-20 season.
- The Premier League will be the top division with the Football League administering the next four divisions.
- Six new teams will be added, along with two promoted teams from the National League creating 100 professional teams.
- Promotion to and relegation from the Premier League will be retained at three places.
- No teams will be relegated from the Football League in 2018-19.
- Football League clubs will vote on the proposals next summer.
- The League Cup will be retained in its current format to include two-legged semi-finals.
- The Football League Trophy could include a group structure of three games and a knock-out thereafter.
- The Football League Trophy could also include Premier League B teams.
- Further discussions are planned on the removal of FA Cup replays, a winter break and the future of the Community Shield.
