I see our main rivals in Scotland these days as Aberdeen. I admire and respect them as a club and one of my best lifelong friends is a Friend of Dolly.
I like how they aren’t generally happy with long ball hammer throwing football even when it worked. As I Celtic fan I can relate to that given we invented sexy fitba in the 60s. Prior to that it was all people running in a funny way in straight lines in black and white, right up to and including when England won the World Cup. After 1967 the game is unrecognisable.
Curious that the Brazil 1970 side came along in short order after 1967. Coincidence? I doubt that.
There are hints of better fitba in the last 2 and a half games.
Previous to the last 3 years or so we were decent to watch but after the season we finished runners up in everything we went more direct.
About the same time Sam Cosgrove came into the team and although his goal record has been excellent the fitba style hasn't.
Back on topic, we've not got a main rival but we have plenty of good rivalrys with clubs. Mainly the OF, Hearts and Dundee Utd.
I also like to think that Aberdeen are high up on the list of most disliked by other clubs.
