The Premier League has labelled the Football Association's governorship of English football as deeply flawed.
The Premier League, which oversees the interests of the 20 Premiership clubs, insists "trust is lacking in the game at every level".
It adds: "The FA board is no longer capable of properly managing its roles. The way of working is unsustainable.
"There is an underlying sense of conflict and alienation between the constituent parts of the game."
The Premier League's views have been submitted to an independent inquiry headed by Lord Terence Burns, who is conducting a review of the FA.
And little has been held back by the Premier League in its calls for English football's regulatory body to be revamped.
PREMIER LEAGUE SAYS THE FA IS....
Outdated and distrusted
Unable to properly manage its roles
Inefficient and the cause of tension
Lacking clarity and in need of restructuring
Not capable of delivering the new Wembley stadium
Failing grass roots football
The report continues: "The tensions that have existed since the creation of professional football continue and there is an underlying sense of conflict and alienation.
"The relationship between the professional and amateur game has never been properly resolved and now is the time to do so."
On the issue of the England national team, which also falls under the jurisdiction of the FA, the report said: "The clubs can feel very detached from the decisions that are made.
"The Premier League believes that the England team 'belongs' to the whole of English football, to the country.
"However, it can often be the cause of tension - the so-called 'club v country' debate.
"It makes sense for the Premier League and the clubs to feel greater, not less, involvement and ownership."
The FA also came under attack for the way it runs the world's oldest domestic cup competition.
Premier League chief Richard Scudamore claimed "clubs feel the FA Cup is not really theirs in any meaningful way.
"This is unhealthy for the game as a whole."
