I say one goalkeeper is enough at under 15's level. You don't want to be changing either one half or changing them one week and rest the next. This doesn't help the goalkeeper. He/ she needs to be playing every week it doesn't do the team any good, as the defenders don't want to be playing with different keepers every week either.
they need to work hard in training and make that clear to them, if the first team keeper has a bad run of games, drop the keeper. And explain to the other keeper that this is there chance to impress.
Keep the same goalkeeper everyweek as this also helps the development, the mind keeps going. |
