The feud between the Blues and Tottenham Hotspur is a fiercest in English football rooted in half a century of clashes and different paths in London derbies. The heated era began in the 1970s with tough relegation fights, including a 2-0 Spurs win that contributed to Chelsea’s relegation. It reignited with the 2015 League Cup final win for Chelsea and the Battle of Stamford Bridge in 2016. In recent seasons, the rivalry has featured title battles and notable cup encounters, including early 2017 meetings that interrupted winning runs.
