The Den and Upton Park have already been covered in some detail. Anfield was only really scary if you were caught on your own or vastly outnumbered.
Cardiff were always up for it, but so were we. I remember a certain Mr H berating another (younger) Mr H for taking such a small mob into the Cardiff end one time. Suffice it to say that they didn't fare too well and were escorted out of the Cardiff end and taken back to where the main Chelsea mob were gathered.
I went to St Andrews a few times but don't remember it ever getting too hairy up there. I do remember being at New Street Station after a match and being told about "a mob of a thousand black Birmingham fans". If there were such a mob, I never saw them.
Which brings us to Elland Road.The on and off field rivalry between ourselves and Leeds has been well documented. It's one of those unique rivalries that goes back decades, and transcends time and geography. The players hated each other even before the 1970 Cup Final, which itself served to exacerbate the already simmering hostility between the fans. There was a famous incident when a coach load of Chelsea met a coach load of Leeds at a motorway service station. Such encounters were not uncommon in those days. If memory serves me well, the Leeds fans that day came off much the worst.
Most trips to Elland Road were the usual thing. Police escort to the ground, segregated fans, but with isolated (and sometimes not so isolated) incidents, small scale skirmishes taking place in and outside the ground. One occasion, I think it might have been during the ban, getting off the train we were met - almost escorted, by a small mob of Leeds fans, who were acting fake-friendly in plain sight of the old bill. They were soon chased off, and so we got to the ground with no further incidents. I was one of a small mob of Chelsea who managed to get separated (by hook or by crook) from the main Chelsea mob, watching the match from the long terrace at the side of the ground. At half time, I decided to go to the bar. On my own, I ran smack into this same little mob of Leeds that had been so "friendly" as we left the station. This curly haired little twat stood at that front of their mob, acting the hard man and getting lippy. Telling me I was dead. I told him I'd take him with me - I was never any kind of hard man, but there was a time when I had all kinds of front.The little f**ker kicked my shin and I kicked him back. So there was me and this northern runt trading kicks, his backup mob salivating, ready to launch themselves into the attack, and I'd just about resigned myself to getting an almighty kicking, when Mr H |(the younger one referred to above) and a few of his mates appeared behind me. "f**king Northern w**kers" one of them hissed with disdain - you've never seen a mood change so quickly. Those Leeds fans, moments ago baying for blood, were now backing away, quaking like the Yorkshire sheep they were. They ran a mile.Thanking my rescuers, I was told, no problem. We were watching you and saw that lot coming from the other way.
