Yeah Lyon is basically a european all-star team and they have trouble against, like, the NC Courage. The gulf isn't as big as it was 5 years ago, but the USA still has a massive participation advantage for girls in youth and women in college, generally thanks to Title IX. Like, the USWNT B-team might stand a chance of winning the WWC. They wouldn't be favored (the way the A-team is), but the talent pool is so deep that you can take out your Ertzes and Lloyds and Lavelles and still have a squad that will fucking crush all but the top 6-8 WNTs.The Euro heavyweights like Lyon are probably better than any club in NWSL, but even the best Euro leagues are extremely top heavy.
The bottom half of the French league is semipro at best and would have no hope of competing in NWSL at all.
BTW, a more comprehensive Club World Cup type comp would be GREAT in women’s soccer.
I've said for a while that they should send a B-team to the Algarve Cup, just to see how it goes, while the A squad plays their SheBelieves Cup. You know, on different days, with different coaches, 6 time zones away. Can't get enough experience, and there really aren't that many good women's tournaments.
As for a (true and hyped-up) women's Club World Cup, that's such a good idea that I'm sure it would have existed years ago if Chuck Blazer were still alive. Can you imagine a league-position-based grudge match, NWSL vs English WSL? I'm willing to bet you could find a way to do a true global CWC twice in a WC quadrennial cycle, hosted once in the US and once in Europe. I would watch the fuck out of that. You could let minnow nations each send their WNTs, too, once you put 'em through some qualifiers.
