if there really is a "Frankostein club", it's Madrid. No domestic competition to speak of and a team made up of their first choice picks from around the world either bought for eye-watering sums or poached on a free. All based on a history of state sponsorship and geographical.location.
With their advantages, they should be winning the CL every year, especially with English teams having an attritional domestic league to contend with.
I think the football world outside of Madrid are rather enjoying seeing their balloon of hubris popped.
