Okay, I'll stick my neck out and declare my support. I've been mocked before for why I support them, but here I am again.
I like them for two reasons: first, because I care about aesthetics and I think theirs is the most elegant uniform in the entire Premier League. Secondly, they are the perennial underdogs to their arch-rivals Arsene-al, and underdogs must be supported at all times (except when they're playing your team, which in this case doesn't apply because they won't ever take on Pakistan in a cricket match). This is particularly true when the underdog is more of a dark horse, one with an outside chance.
I hope they can win something this year, otherwise Kane, Alli and co will leave for greener pastures, which would be a shame, since they've got such a good combination for the last couple of seasons. It will be tough doing it at Wembley too.
