Hart-broken, Hart-attack, Hart-stopping, Hart-less...the puns keep on coming while the Premier League struggles to comprehend just what has happened to Manchester City's former goalkeeping prodigy.
Rampaging off his line to claim the ball, the Englishman left it too late to call Nastasic off from his own attempt to clear the danger, leading to both players being taken out of the game for Torres to score for Chelsea.
The goal made it 2-1 in favour of Jose Mourinho's visiting title-challengers, with Hart's costly mistake denting City's own immediate table-topping ambitions.
Manuel Pellegrini couldn't bring himself to back his goalkeeper after the game, who has also made other damaging errors in goal for the club of late, most notably in their surprise loss to Cardiff City.
Unless Hart can return to his previous form as the league's top shot stopper he may feel his place under threat with Iker Casillas eyeing up potential January escape routes from his continuing misery in Real Madrid.
