English football's new independent regulator cannot be a "sledgehammer", says Premier League chief executive Richard Masters.
It aims to prevent clubs going out of business, give fans greater input and introduce a more stringent owners' and directors' test.
"Regulation brings with it many challenges," Masters said.
"This needs to be a very precise regulatory tool and not a sledgehammer, otherwise it might take football sidewards, or even backwards, rather than forwards."
The Premier League was understood to be wary of a regulatory body when the proposals were announced in April last year.
The league says it is "vital" a regulator does not lead to any "unintended consequences" that could affect its global appeal and success.
