Cole Palmer's 101st-minute winner against Manchester United provoked scenes Stamford Bridge hasn't witnessed for a long, long time; after Chelsea's new hero crashed his strike in off the hapless Scott McTominay, the stadium erupted - a spontaneous combustion of emotion, frustration and pure relief.
As the camera vibrated uncontrollably, Palmer wheeled away aimlessly in celebration, his team-mates falling over themselves to get a piece of him as he evaded them in the same way he had eluded Manchester United's defence all night long; on the touchline, a bellowing Mauricio Pochettino looked on the verge of tears before he was mobbed by his coaching staff.
Granted, the Blues should never have been in a position where they required a questionable penalty decision and a last-second goal to win this game 4-3, having been masters of their own downfall as they threw away a two-goal lead to trail 3-2 after 90 minutes - but Pochettino simply must harness this energy to push on to better things in what remains of the season. His future as Chelsea manager depends on it.
