The Blues started their season horribly but have won their last two, scoring six goals in two games against Fulham and Burnley.
Arsenal are a whole different proposition, however, with the Gunners flying high near the summit of the table.
Before the international break, Mikel Arteta's side beat title rivals Manchester City 1-0 thanks to Gabriel Martinelli's goal.
So they're likely to head into their clash against the Blues with all the confidence in the world.
But Mauricio Pochettino's side have some newfound form of their own, and they won't want to give up any ground on home turf.
