During the SAF era, I honestly would've placed Man U at #1 (SAF IMO was a bully who had the ear of the refs), but they've since struggled to remain relevant in the 13 years since his retirement, so I don't quite feel the same way about them anymore. Also they were the stereotypical glory-hunter club.
I'm honestly more ambivalent about Liverpool than most on here. When I first started supporting Chelsea (early 2000s), they themselves were struggling to remain relevant, and them fixating on their history from the early 2000s to about the late 2010s (when they started consistently becoming a title threat) was more hilarious than anything else. Perhaps if I lived closer to Anfield, or if I started supporting Chelsea during the 70s/80s (when Liverpool were the glory-hunter club of choice), I'd feel differently. Brisbane is full of Liverpool fans, but I just kinda...ignore them. Granted, there were those spicy games in the mid-to-late 2000s, but we usually came out on top during those encounters, anyway.
Ofc I hate Crotchenham; that's the duty of every Chelsea supporter. The main reason why I decided to travel down for the game against Western Sydney is because I didn't want to meet any Crotchenham fans (I honestly don't think I've met any before, so I guess I'm blessed). They're fun to goof on though, and from a patriotic POV, I admit that I didn't want Ange to do badly with them.
Arsenal have always been in my Top 3. During the early 2000s, they were another glory-hunter favourite, and they constantly had the wood over us until after about 2004 or so (even in 2004-05, I don't think we actually beat them in the league...). And now under our current 'management', they have the wood over us again. Watching Drogba bully Senderos constantly in the late 2000s was fun.
Historically I didn't hate City, but in-between the FFP dodginess and the whole Maresca tapping-up affair, my opinion of them has certainly soured.
Obviously have never thought much of Barcelona (or UEFAlona).
Dishonourable mention goes to QPR. Like I've said, they're a cruddy, two-bit skidmark of a club, and their supporters are total lowlifes. And they would be on any planet. I can't imagine that the Martian QPR fanbase is any better than Earth's QPR fan base.
Crystal Palace's supporters aren't above mocking us on online forums, so I'm happy when we beat them as well, even though they've never been serious rivals.
Don't really care that much about Fulham or West Ham (again, they've not been serious rivals in my time supporting Chelsea), and Leeds have generally been irrelevant since I've started supporting Chelsea (they were declining by the time I started supporting Chelsea), so I feel much more detached RE Leeds than older Chelsea supporters would.
Milwall come across as a bunch of thugs, but I don't even remember the last time we even played them, so again there's that same detachment.
