As a modern goalkeeper you have to be almost as technically skilled as your teammates. You have to be almost perfectly two-footed if you want to have a chance of progressing through the youth categories as an elite goalkeeper. Talent is one thing, but talent alone will not get you there. If you can combine talent with hard work, you are already a step in the right direction.  In order to have a good right and left foot, you have to train hard on both feet. Even if you don’t always succeed, if it’s not perfect and sometimes even boring, only then will you improve and both feet will make progress.
