The topic about Mexico's chances at having ten straight CCL winners made me create this topic. In how many of the next 10 CCLs will the last remaining non-Mexican club be from MLS (including Canadian clubs)? If you predict the last remaining two or more non-Mexicans clubs to be eliminated in the same round, consider whichever club loses their aggregate by the fewest goals to be the last remaining one.
I would imagine more than CFU clubs and Central American clubs, but would not be surprised if we see many all Liga MX semifinals, maybe 1/3 to 1/2 of them.
I answered the question before reading your definition of last remaining one. I assumed those eliminated in the same round were equal. Now we just need to wait 10 years to see the correct answer.
