Marcelo Bielsa's side dominated for much of the ninety minutes in LS11 but were hit by a late blow as Wayne Routledge scored as time expired to hand the Swans all three points as they hauled themselves to the top of the Championship. Here's how we rated the performance.
7 - Had so little to do. Made one decent save in the first half, got down well at the feet of Surridge in the second.
7 - Hard working, good at both ends of the pitch. Supplied decent balls into the box.

8 - Anticipated almost everything that came his way and was excellent on the ball.
8 - In complete control of the men he had to pick up. Stepped up into the play well to intercept and then find a man. Unlucky not to score.
6 - Plenty of effort, the quality wasn't always there when he had the ball. Yellow card left him walking a tightrope but he managed the situation well.
7 - Very good defensively, even when struggling with a knock. That didn't stop him from throwing himself about.
6 - Linked up well in the first half but faded in the second. Wasn't happy to be substituted, presumably unhappy with his own showing.
6 - Was good in patches and put in a full-blooded effort without ever really managing to pick a killer pass and cut the Swans open.
6 - Bright start, worried the Swans down the left and did manage to supply Bamford with a good low cross, but final ball wasn't there throughout.
7 - Involved in so much of what Leeds did that troubled the Swans but at times picked the most difficult option.
6 - Should have got his name on the scoresheet. Played the targetman role well, up until the point it came to put good chances away.
6 - Pace gave Leeds a different option and created a chance for himself. But couldn't find the net on that occasion or from an even better one, late.
7 - Gave Leeds pace on the right and was a real handful.
5 - Only on for seven minutes, unable to make an impact.
