I can never tell if people are being serious in these threads or not. I doubt that there was even a 30 second stretch during that match where more than one or two Real players was putting any effort at all into winning. The Chinese kids were just surging around in a giant mass, and a soccer pitch is a huge space, so Real could have just blasted the ball downfield and outrun the kids pretty easily. They didn’t, because they’re Real Madrid, and they were playing 109 children. I don’t suppose it occurred to them to press their advantage.
Numbers help in some ways, but not at all in others. I say unless there are so many children on the field that the professionals are physically encased in them, the pros kill them in any sport.
Basketball - two lines of children across the basketball court to try to take a charge means hello, unlimited uncontested 12-footers (and if they’re at half court, just run around them out of bounds, come back in, and throw it over them). If the kids try some kind of 20-30 zone (maybe a triangle and 47?), the pros can just slowly walk to the front of the rim, , turn, catch a lob, and lay the ball over the front of the rim, repeating as necessary. The ball never needs to be less than seven feet off the ground. Good luck inbounding the ball on offense, meanwhile.
Football - a serious competition would end after the kickoff either way, as each individual collision would probably have a 20% chance of killing the child or children involved, and a 60% chance of paralyzing him and putting him/them in a coma. The other 20% of the time the kid would run off the field before the full impact, and probably only lose a leg or something. 110 kids can’t block the entire field with their tiny shattered corpses. Ignoring the resurrection problem, every running play would start with seven 260-350 pound men crashing into however many 90 pound kids care to die for the cause, and then one of the fastest, strongest 220 pound guys in the world, with a running start, coming behind them. Somebody’s little baby has to grab that man and put him on the ground. I think he’s going to get a first down, even if it takes a while for his offensive line to carve a path through the ruined futures. On pass plays, pass interference would still presumably be illegal, so after one bump the wide receivers are running free in the secondary, and the kids have to make a play on the ball without hitting the receiver. Probably literally impossible. On defense: LaVar Leap. LaVar Leap. LaVar Leap. Blocked punt.
At a certain point, the extra people just confuse things, anyway, since only a small fraction can really be involved in the play at any given time unless, like Munch said, there’s some kind of hive mind at work. It’d be mostly kids milling around in the middle distance bumping into each other, and then a few kids actually trying and failing to make plays. Even in high school, when my basketball coach used to use J.V. and 8th grade players to put 10-15 defenders on the court to help us break the press, it wasn’t that hard to do, because they’re in each others’ way as much as they’re in yours.
