arch rivals
Longtime fierce opponents
Arch rivals are opponents with an intense, longstanding competitive relationship.
The rivalry is often the most significant for both parties—two teams that always bring out each other's best, two companies fighting for the same market, two politicians who've clashed for years.
The two schools have been arch rivals since the 1950s.
Sometimes written as one word: archrivals.
