And further to that, is the system over in UK different to what it is over here?
Here, there are no “competitive” leagues in younger age groups, up until about age 11 iirc. Only then do kids get “graded” at the start of the year and are put into appropriate level teams. And unless they are in the very top rep sides, it’s still the norm to give every kid a fair go.
When my boys were playing football years back, the local club had multiple teams at each age group, especially the real young groups. And the season was basically Intra club friendlies against each other team. And smaller clubs just played all “friendlies” against nearby teams. Didn’t keep scores or report on victories or defeats. The kids often didn’t know or care when they were walking off at the end. So long as they enjoyed it and had a kick with their mates.
And, if there was an obvious mis-match of skills between 2 sides, at some point the players might be swapped around to even things out.
It’s also the norm in the young groups to get the players playing in different positions from game to game or within games. Every one has a go defending, attacking, keeper etc.
