A record crowd filled the old Skydome in Toronto for a soccer game in March between two MLS teams, Toronto and the LA Galaxy. It wasn't even a league match, although it wasn't a friendly, either. Instead, it was a quarter-final in something called the CONCACAF Champions League, a regional competition designed to replicate what the UEFA Champions League has in Europe.
This competition has been going on for several years but Americans haven't really cared about it. Teams have almost deliberately fallen-down after being chosen, including the Galaxy, whom I once saw lose a two-legged tie to Puerto Rico's A-League outfit in front of maybe 2,000 people.
