Watching it again, while not a foul, he should've stopped play to check on injured player right after GK collision...but negative energy of game was more a reflection of coaches and kids than the ref.....
@dad4 yes that shove did lead to the retaliation, maybe a yellow for the shove would've prevented it....so you make a good point I just don't see the ref as the only issue here
At that age? Not sure that's true. Otherwise the instruction would develop for any player in such a situation to dive and simulate to stop a promising attack. At U12, o.k.
Because the shove took place outside of the lines, I"m not sure the ref saw it. The ref had already cautioned the GK for inappropriate behavior a few seconds earlier. I doubt if he had seen the shove, he would have let it slide. From the earlier discussion, that's where it's up to a player to do the Neymar, and sell the foul so the ref sees him go down.
The offside call is on the AR.
