The Football Association has an official inquiry into the formation of the Super League and the involvement of the six English clubs - which also included Arsenal, Chelsea, Manchester City and Tottenham - had got under way last week.
It also reiterated its desire to ensure any return threat of a breakaway division was thwarted.
At the same time, the Premier League has taken action to prevent a repeat of its clubs threatening to breakaway in response to the Super League fallout.
Six top-flight teams, including Manchester United and Liverpool, announced late on April 18 they were joining a new continental competition called the European Super League, only for it to collapse amid intense pressure within 48 hours.
A new set of measures have now been put in place by the Premier League to stop any future attempt of a breakaway division, which include additional rules and regulations and a new Owners’ Charter that all club owners will be required to sign up to committing them to the core principles of the competition.
Fan protests in the days that followed the Super League 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.

“Since we became aware of the European Super League our priority and focus has been on preventing it from happening, both now and in the future.
“Throughout this period, we have been in ongoing discussions with the Government, the Premier League and UEFA. In particular, we have been discussing legislation with Government that would allow us to prevent any similar threat in the future so that we can protect the English football pyramid.
“Last week, we started an official inquiry into the formation of the European Super League and the involvement of the six English clubs. We wrote to all of the clubs to formally request all relevant information and evidence regarding their participation.
“Once we have the required information, we will consider what appropriate steps to take. Clearly what happened was unacceptable and could have caused great harm to clubs at every level of English football.
“The fans have played a vital and impactful role in helping to stop the European Super League from happening, and we understand their frustrations. 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 events of the last two weeks have challenged the foundations and resolve of English football. The Premier League has prepared a series of measures to enshrine the core principles of the professional game: an open pyramid, progression through sporting merit and the highest standards of sporting integrity. These measures are designed to stop the threat of breakaway leagues in the future.
“Opposition to the proposed Super League united the whole of football, with the fans’ voice clearly heard. The Premier League recognises the strength of feeling and the right of fans to know what is happening. 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.
“The actions of a few clubs cannot be allowed to create such division and disruption. 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.
“In addition, 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:
Additional rules and regulation to ensure the principles of the Premier League and open competition are protected
A new Owners’ Charter that all club owners will be required to sign up to, committing them to the core principles of the Premier League
Breaches of these rules and the Charter will be subject to significant sanctions
We are enlisting the support of Government to bring in appropriate legislation to protect football’s open pyramid, principles of sporting merit and the integrity of the football community
“ We will work with the fan groups, Government, UEFA, The FA, EFL, PFA and LMA to defend the integrity and future prospects of English Football.”
