Is practice twice a week enough to become a top-notch goalkeeper?
A. As with most endeavors, you get out of it what you put in. All good goalkeepers who reach a higher level work extra sessions. These are usually sessions with friends who can shoot on goal. Even field play will make you a better goalkeeper. Anything you can do on a daily basis to improve your skills will help. If you only want to play recreational soccer practicing twice a week is more than enough.
