As someone who never played soccer as a kid and only starting learning the nuances of the game as my son got involved, it seems to be one of the only sports where "players size" doesn't play a major factor at all.
My son was "undersized" for many years, so he worked on his technical ability. He is almost 11 and has caught up to the other kids in terms of size and has great skills as well. Sometimes being undersized makes you develop tools as a player that "bigger" kids don't need to use at a young age.
