The prospect of European soccer leagues playing regular-season matches in the U.S. has been a highly tantalizing prospect for many promoters and stadium operators for years.

Recent legal developments have now made such events truly possible, but the final and critical step of those leagues actually agreeing to do so remains uncertain.

Earlier this month, FIFA settled a long-running lawsuit filed by promoter Relevent Sports, controlled by Dolphins owner Stephen Ross, that had alleged antitrust violations regarding the global governing body’s prior policy emphasizing leagues’ playing official matches within their own respective territories.
