The Premier League has taken action to prevent its clubs threatening to break away again in response to the failed European Super League plans.
Six top-flight teams, including Manchester United and Liverpool, announced on April 18 they were joining the newly-formed ESL, only for it to collapse amid intense pressure within 48 hours.
A new set of measures put in place by the Premier League on Monday includes additional rules and regulations and an owners' charter that all club owners will be required to sign up to – committing them to the core principles of the competition.
"The actions of a few clubs cannot be allowed to create such division and disruption," a Premier League statement read.
"We are determined to establish the truth of what happened and hold those clubs accountable for their decisions and actions. We and The FA are pursuing these objectives quickly and appropriately, consulting with fans and Government."
The Premier League insisted events during the last two weeks had "challenged the foundations and resolve of English football".
Fan protests in the days that followed the ESL announcement, on top of widespread criticism from the footballing world, resulted in most of the 12 European clubs – including all six Premier League sides – involved in the proposed breakaway pulling out.
A statement continued: "The Premier League, supported by The FA, is taking the following actions to protect our game, our clubs and their fans from further disruption and uncertainty.
"However, we cannot condone the violent and criminal behaviour that took place before the scheduled Manchester United vs Liverpool match, which The FA is now investigating."
The Premier League added: "We are committed to maintaining close dialogue with supporters and their representatives, as we work with The FA and Government to identify solutions, but ask that all protests are peaceful.
"The actions of a minority of those present at Old Trafford on Sunday have no justification and will be investigated by the Premier League and The FA as well as by the Greater Manchester Police."
