Teenage midfielder Jobe Bellingham was again Sunderland's hero as they ended Leeds United's seven-game unbeaten run with a superb Championship victory to make it two from two for interim head coach Mike Dodds.
Leeds' fearsome form under Daniel Farke, with three wins in a row during their in-form sequence, made them a daunting opponent but the Wearsiders executed a game plan to neutralise the attacking threat that brought them eight goals in those victories.
It took until 12 minutes to go for the deadlock to be broken, after lots of chances at either end, as Bellingham bravely put his head in where it hurts with Leeds goalkeeper Illan Meslier out to smother, and guided it into the net.
