Thomas Tuchel managed Chelsea for 100 matches. It was an ironically round number to end on given the significance of the century, how hard it is to get that far at Chelsea and how brutal the decision to mention it in the farewell to him was.
By now it is no secret that the second 50 didn't quite match up to the first. Conceding more than double the amount of goals and losing nearly two times as many matches, the proof was in the pudding. Chelsea had been slipping for a while.
Another intriguing point to note, and one that is even more relevant with Graham Potter's first international break on the horizon, is that Tuchel's record after these windows was poor.
