A stoppage-time Igor Vetokele strike sealed a 2-1 victory for Charlton Athletic against AFC Wimbledon in a pulsating London derby.
It was a cruel blow for the Dons who were more than worthy of a point against an Addicks side who looked disjointed and lacklustre for large parts of the encounter.
Tenacious in the tackle and quick on the break, Wimbledon were well worth their 24th minute lead as Michael Folivi tapped home a free-kick after good work from Terell Thomas.
However Charlton could have equalised just past the half-hour mark as Lyle Taylor volleyed an effort over the bar with the goal at his mercy.
The second-half opened with Addicks boss Lee Bowyer sent to the stands before the Addicks somehow found an equaliser through a thunderous Naby Sarr free-kick (51).
It sparked the visitors into life and they slowly began to turn the screw but left it until the 91st minute to seal an unlikely victory as Vetokele stabbed home after a scramble in the box.
The result leaves both sides as they were in the table – Charlton consolidating their position in the Play-Offs and Wimbledon bottom – but crucially now seven points from safety.
