Also, two new derbies will come of this: a match between the winners of the MLS and the Liga MX, and an All-Star match between the teams.
I thought I'd seen mention of a new SuperLiga type thing, to be played in July-September when there's no Champions League matches (for Canada/USA/Mexico at least). Did that fall through, or was I dreaming something?
