There are many different factors involved in talent identification.
In general, scouts look for good technical ability, agility balance and co-ordination in movement, football intelligence in and out of possession, decision making, problem solving, strong desire, good attitude, confidence, game awareness, personality and athleticism.
However scouting can be age specific, Why? because as a player matures different attributes become more apparent, i.e physical strength, pace, power.
Goal Keeper specific in general scouts look for good communication, handling, kicking from floor and from hands, shotstopping, catching, throwing, agility, balance, co-ordination, awareness, decision making, desire, punching, personality, touch, control and passing and athleticism.
As a Goal Keeper matures again with age, his actual height and potential height in full maturity do become factors in the modern game.
Some attributes can be developed through good coaching, i.e technical (passing, shooting, heading, tackling, crossing the ball, striking the ball, dribbling, running with the ball, touch, control etc.
Scouts also look for a player which does or tries something that makes them stand out from the others, they have 1 outstanding attribute or show sufficient potential to be developed.
Lots of scouts only recognise the big tall stronger players as these obviously stand out from other players, these players are normally born in the 1st few months of the school year i.e September, October, November, December, making them the oldest in their class or team, the younger players can easily get overlooked as they are normally smaller and less physically developed, these are normally late developers and need more time and consideration and it is very important to consider this in any decision making for long term player development.
However scouts, coaches or parents can’t give players the desire, high work rate, effort, commitment and determination required, this can only come from the player himself.
