right i think i might have a candidate,and i know this guy,well when i say i know him ive chatted to him a few times hes lived in blackpool for years,in fact man city signed him from blackpool
and that guy is paul stewart,we sold him to spurs (so possibly 5 derbies,6 if you inc pool v preston) then he went to liverpool,and i think he played for celtic,but i dont remember him playing for bristol city/rovers
and wether or not he scored in all of them?
