I guess you could be a really good player for your age in the age group U13. But as a 13 year old, your body is still developing and therefore you arent as strong or quick as you would be if you were 18 since your hormones have grown much more and are stronger than if you are 13 but you can still be very good, even as a 13 year old which you probably are. If you keep up the good soccer and you continue improving you can achieve your goal of a proffesional soccer player.
