Following the failure of the European Super League, there have been calls for reform at a Premier League level.
However, the proposal collapsed in a matter of days after major backlash forced all six English clubs to withdraw.
Now, according to a report from the Sun, those same clubs want to see major Premier League reform.
The report states that one of the ideas being discussed is for a so-called British Super League, which would see Celtic and Rangers invited to leave the SPFL and join the Premier League.
The proposal is yet to be fully fleshed out, with talks ongoing as to how many teams would be involved.
Some are said to be in favour of a short-term expansion, while others want to condense the league down to just 18 clubs.
It is also claimed that discussions are ongoing about an end-of-season play-off, similar to the system used lower down the football pyramid.
In order for any new reforms to pass, they will have to get past a Premier League shareholders vote.
The 20 clubs currently in the league make up the shareholders and a proposal would need the support of at least 14 clubs in order to pass.
It is claimed that an expanded Premier League would receive the backing of UEFA, FIFA and the Government, while Celtic and Rangers’ rivals in the SPFL would also be keen on the idea as it would end their dominance.
One club source told the Sun: “Whether or not the Super League was going to happen, we all feel that the Premier League has to be changed and improved. It is time we opened it up to Rangers and Celtic. That would make sense for everyone.”
