Tottenham. Just dislike them, their choices of managers over the years, Harry Kane, Son, and so many of their fans.
What particularly annoys me about the fans is that they are completely lacking in self awareness. At least Chelsea fans know that other fans dislike them.
Spurs fans seem to think that they are everyone's second club. They also know literally nothing about football that's past the end of their Spurs nose.
Fun fact: Spurs last winning the league was closer to Queen Victoria being alive than the present day.
I also still harbour an irrational dislike of Swindon.
