No, players are allocated centrally following the Trials that take place in May. This is so all teams are balanced as much as possible in terms of age, numbers, ability, confidence and the positions that children play (it’s no good one team having three goalkeepers with others having none). If a manager or assistant has a son or daughter playing they will automatically join their parent’s team unless otherwise agreed. If siblings fall within the same age group they will also be allocated to the same team.
