Chelsea wasn't really person to person trouble on a large scale...the club gave them some of the north stand ( at least that's what i recall)and they then got on the pitch and trashed the posts etc.....some scuffles but in truth there were simply too many of them for us.
No...the majority of the Spurs nutters came across the corner from the east terrace, we had a torrid time fending them off in the north...there were a lot of injuries.
...at least that was my memory as a 17 year old.
