Patrick Bamford bagged twice at Kenilworth Road as Marcelo Bielsa's side scored a late winner which cancelled out a James Collins leveller. United made it three wins on the spin in league action, here's how Graham Smyth rated the performance.
1. Kiko Casilla
7 - Assumed his traditional spectator role in the first half. Could do nothing with the goal, made a sharp save immediately after.
2. Stuart Dallas
7 - Appeared to start the game at left-back, soon moved into the middle. Shackled Shinnie, contributed higher up the pitch. Energetic and efficient.
3. Gaetano Berardi
6 - Faced a real battle with Harry Cornick but competed well, stuck with his man for the most part. Replaced by Cooper for the latter stages.
4. Ben White
8 - Comfortable in the first half, even when Leeds looked stretched by Luton's counter attack. Claimed a brilliant assist and fought hard in the second half.
5. Luke Ayling
6 - Got forward well in the first half, produced some excellent deliveries. Beaten for the goal and wasn't as effective in the second half.
6. Kalvin Phillips
6 - Set out to stick to Izzy Brown, wasn't an easy task. Brown looked dangerous when he got free and in one such moment produced the cross for the goal. Phillips stuck to his task throughout.
