Despite the controversy around Chelsea's late 2-1 win against West Ham, a match in which they were fortunate to get all three points following a hotly debated VAR call, Thomas Tuchel's side showed a part of their game that has been missing this season, and for a while beyond that.
Tuchel saw his side once again labour in attack, once again let themselves down in defence and for once, mount a serious comeback. Although the phrase 'mentality monsters' is being kind - especially considering the shambolic nature of the first goal and the second that ought to have counted - the response to come from behind was refreshing.
The German has already labelled his team as soft this season due to being easy to beat and shipping poor goals, that didn't change too much against West Ham, but the substitutes that were made did change the game and on paper, Chelsea did something they don't do that often.
