The rivalry between the Blues and Tottenham is a fiercest in English football rooted in decades of competition and different paths in London derbies. The heated era spiked in the 1970s with tough relegation fights, including a 2-0 Spurs win that helped Tottenham survive. It reignited with the 2015 League Cup final win for Chelsea and the Battle of Stamford Bridge in 2016. In recent years, the clash has featured title chases and notable cup encounters, including 2017 clashes that interrupted winning runs.
