The documents reveal that the "initial guests" will be Atletico Madrid, Borussia Dortmund, Marseille, Inter Milan and AS Roma.
The documents also state that a decision will be taken in November 2018.
One senior Whitehall source said: "Government hasn't been told about any of this, which suggests the Premier League has also been kept in the dark".
In their report, they assert that Bayern chairman Karl-Heinz Rummenigge had "betrayed" the smaller clubs around Europe by being involved in plans to undermine the Champions League, a competition that is becoming increasingly hard to reach for teams from lesser footballing nations.
The 11 founder clubs will be guaranteed membership for 20 years, whilst there will also be a second league under the European Super League.
Such talks have reportedly lead to concessions made by UEFA to the clubs for a greater share of the Champions League revenue in order to keep the big sides in the competition.
Rummenigge says he will consult Bayern's lawyers, but insisted there is no question of the Bavarian giants leaving the Bundesliga to join a super league. The vote in favour of the reform agreed between UEFA and the ECA was unanimous.More news: Dense smog chokes Delhi-NCR, air quality hazardous in several areas
What is the lure of the European Super League?
It sounds nice, really nice, because it would mean a lot less games and much more money.
Through breaking off of their national competitions and forming a league where only the most elite players were to partake, the Super League would compete with the NFL and NBA and benefit from huge television rights deals.
What will happen to the Champions League?
During the week there were a number of leaks printed by Der Spiegel in Germany and subsequently published by the world's media outlets regarding FIFA and world football in general.
The documents obtained by Der Spiegel, however, claim that this would allow the new league to avoid running afoul of European law by not ending the competition entirely.
The documents claim they are among 16 clubs who would leave their domestic competitions to play in the new league as early as 2021.
