Contrarily this now gives the ESL trio time to build this project without the threat of Uefa. The fact this has (or is going to be) determined in a Swiss court was a genius move as it juristicts the current movements of FIFA and UEFA by their home country.
So now Floro can build teams teams and leagues who agree to join. Can the ESL guarantee more downside than the CL to teams from Portugal, Spain, Italy, Netherlands and possibly Russia, Turkey.
If the answer is yes then we can very well see a breakaway with a ESL consisting of Spanish, Italian, Portuguese teams and a CL consisting of English, French (well PSG), German teams.
EFL can easily win the global tv viewership if they do the opposite of the CL and focus on streaming service + Freeview rights sales (obv they would be blacklisted in the UK because of government intervention, and they say no monopoly exists lol).
From this you can see that the key battle ground would be Germany. The CL would just become a glorified EPL cup without the German, Spanish, Italian sides while the ESL would appear kind of week with just the top Spanish and Italian sides.
The last to join would be the EPL and only after proof of concept and proof of success.
This is how I see it playing out in all likelehood. It would be a marathon, not a sprint as Florentino foolishly initially thought.
