The semifinals are set, and both were settled the hard way. England needed extra time against Norway before Bellingham found his second and closed it out, 2-1. The other went further and stranger. Argentina and Switzerland turned on a single moment in the 72nd, when Embolo dove into a challenge, drew a second yellow through VAR, and left his side a man down for the rest. Until then Switzerland had been the better team, which is what made the unraveling hard to watch; a match slipping away not on merit but on one reckless instant. Argentina pushed, the game stretched into the last of extra time, and Lautaro Martinez settled it in 120+1. There is a lesson in it somewhere about how little it takes to undo an hour of good work.
