Celski nema ziadneho "uhlavneho nepriatela", lebo je to maly klub, co sa vacsinu svojho zivota potacal v nizsich sutaziach a na spodkoch tabulky :))) bueheheh

Chelsea do not have a traditional rivalry on the scale of the Merseyside derby or the North London derby because their West London derbies with Fulham or Queens Park Rangers have not been as prominent over the years since the clubs have often been in different divisions. A 2004 survey by Planetfootball.com found that Chelsea fans consider their main rivalries to be with (in order): Arsenal, Tottenham Hotspur and Manchester United.[78] Their rivalry with Tottenham Hotspur is said to have developed following the 1967 FA Cup Final, the first cup final held between two London clubs. Additionally, a strong rivalry with Leeds United dates back to several heated and controversial matches in the 1960s and 1970s, particularly the 1970 FA Cup Final.[79] More recently a rivalry with Liverpool has grown following repeated clashes in cup competitions
