Newcastle earned a massive victory at Leeds in their fight to avoid relegation thanks to Jonjo Shelvey's 20-yard free-kick.
Eddie Howe's side had only won once all season prior to this energetic and tempestuous encounter where both sides struggled to make the most of first-half chances.
But after Newcastle goalkeeper Martin Dubravka saved Dan James' point-blank shot and Illan Meslier palmed Shelvey's volley away, the visitors finally found a breakthrough.
The goal came from a brilliant run by substitute Javier Manquillo, who was brought down on the edge of the box.
Shelvey stepped up and fired past Meslier, who perhaps should have done better given the ball went in on his side of the goal.
