I have watched him several times (=>
https://footballia.net/players/fahrudin-jusufi), he never stroke me to be the prototype of a modern full back.
He could go forward sometimes but that's it, he was rather a typical full back of the 60's, mostly acting like a central defender in a side, like 65 ATT & 65 AGG style of side back, same for his technical skills, probably in green but nothing exceptional by today's standards.
