You've got to remember he's playing other 9 year olds Australians (who arent exactly known for their football skills). That's why he looks so good tbh, he probably will be a very good player, but just dont go getting too excited about him yet.
Apparently we (Utd) are after that Juan Carlos Chera guy irl as well, the 10 year old Brazilian who's training with Santos iirc. I've seen footage of him playing against people 2-4 years older than himself and he absolutely rapes them. We will, however, have to wait like 8 years to sign him ffs
