Interesting.
18 clubs only. 5 of them English.
If they did this based of most valuable clubs, this would be the make up of the league.
1. Real Madrid
2. Manchester United FC
3. FC Barcelona
4. FC Bayern Munich
5. Liverpool FC
6. Manchester City FC
7. Chelsea FC
8. Tottenham Hotspur FC
9. Paris Saint-Germain FC
10. Juventus
11. Borussia Dortmund
12. Atletico Madrid
13. Inter Milan
14. FC Schalke 04
15. AS Roma
16. Napoli
17. Olympique Lyonnais
18. Ajax
This would leave the 10th most valuable football club in the world out
10. Arsenal
18. West Ham
19. Leicester City
21. Everton
22. AC Milan
24. Benfica
25. Valencia
Personally, if it was left up to me I would stick with the CL and forget this but!
England (Man Utd, Man City, Arsenal, Chelsea, Liverpool)
Italy (Juventus, AC Milan, Inter Milan)
Holland (Ajax)
Portugal (FC Porto)
France (PSG)
Germany (Bayern, Dortmund, Schalke)
Spain (Ath Madrid, Real Madrid, Barcelona)
18th Team (Galatasaray, Celtic FC, Shakhtar, RB Salzburg, Zenit, Olympiakos or Kiev)
English clubs are a combined value of 8.578 Billion, I wouldn't leave that considering the next league on the list is less than half at 3.938 Billion (La Liga) followed by Germany 3.275B, Italy 1.877B & France 1.278B
If anything the English league should invite a couple of big Scottish clubs into the PL.
