Ji Dong Won struck in injury time as Sunderland dramatically beat Premier League leaders Manchester City 1-0 at the Stadium of Light today.
The result left City ahead of second-placed Manchester United on goal difference alone, after they failed to make the most of their local rivals' shock 3-2 defeat by relegation-threatened Blackburn Rovers at Old Trafford yesterday.
There were barely ten seconds left of added time when Ji, on as a substitute, was played in by Stephane Sessegnon. The South Korean forward employed nimble footwork to round England goalkeeper Joe Hart, before slotting home from close range.
Victory lifted Sunderland to 13th place, six points clear of the relegation zone.
City substitute Micah Richards nearly won the match for the visitors with two minutes left, when he saw a header come back off the crossbar.
In the first half, City striker Edin Dzeko was denied by Simon Mignolet and the woodwork. Dzeko's 32nd-minute shot was blocked by the keeper and three minutes later the forward clipped the bar, while Samir Nasri's effort was cleared off the line by Craig Gardner.
But Sunderland could have been ahead early in the game, when striker Nicklas Bendtner was left one-on-one with Hart only for the keeper to come out on top.
And one of the best chances of the second half fell to the Black Cats, when Sessegnon outpaced the City defence only to screw his shot wide with just Hart to beat.
