It is a mantra that has been drilled into the Chelsea squad since he took over six weeks ago and has helped the Blues earn four points in the past two games without playing well.
Last night, Chelsea had to dig deep again against Brentford to earn a fifth clean sheet in a row, and they have now gone nearly nine hours without conceding a goal.
After surviving sustained periods of pressure at Aston Villa to win 2-0 on Sunday, Potter's side had to survive a host of dangerous moments last night before a late push for a winner that almost saw their substitutes snatch victory.
In large parts, it is down to a mentality shift in the squad which had started to lose some of the values learned in the early days of Thomas Tuchel's reign at Stamford Bridge. The German said he wanted Chelsea to be "the team nobody wants to play against", and that approach led them to their Champions League triumph of 2020.
