for me it was back on fm07 . i was playing fulham fc . in the second or the third season i bought a goalkeeper named Piotr Czaplinski a polish youngster . after i saw his attributes in GK i was impressed and after loosing Anti Niemi to Milan on a free i was forced to use other golies . I used 2-3 different ones without any success and then I met him . he was 18 or 19 years old when I started to use him as my 1st choice golie . after a season in the first team starting 90% of the games for my 1st team he became a "wonderkid" and gained a cap for the major team of Poland when i became his favourite personal
so "wonderkids" are usually made by developing by thier managers rather than born such .
