Leeds moved out of the Premier League relegation zone as Junior Firpo's second-half goal gave them a crucial 1-0 victory over bottom club Southampton in Javi Gracia's first game as manager.
In a tense and frantic match, left-back Firpo found himself in space in the box after Jack Harrison's flick to slot home under Gavin Bazunu and send Elland Road into raptures - and his team towards a priceless three points.
Prior to that the game had been balanced on a knife-edge, played out in front of an anxious crowd and between two sides knowing a single costly error could see them staring into the abyss.
The win is Leeds' first in the league since 6 November and takes them to 22 points, a point and a position above 18th-placed Everton.
The defeat for Saints - their first under caretaker boss Ruben Selles - means they stay bottom, four points from safety.
