If you extend it until 2007, Bojan Krkic would be one of them. He started his career at the age of 17 for barca and literally scored 26 goals for the club.
Fati is still just 20 n i hope he changes and also miranda has been solid for real betis for couple of seasons now n he has been linked to ac milan to become d backup option for theo Hernandez
Juan Miranda has just won Olympic gold medal and recently moved to Bologna where he will play Champions League football, so i consider Miranda is not a failure.
