Whites no 9 Bamford bagged his first ever Whites treble by completing a rapid 19-minute hat-trick to ensure United made their authority count after a dominant but goalless first half.
The victory sent United third and Graham Smyth, the YEP's chief football writer, hands out the scores.

8 - Didn't have too much to do but when called upon was brilliant. Made two big, big stops. Taking to the Premier League with ease.

2. Stuart Dallas
8 - Struggled to contain Grealish in the first half but recovered to defend brilliantly in the second and contributed to attacks.

3. Luke Ayling
8 - A captain's performance. Some lovely passes, some vital challenges, a goalline clearance. Had his hands full but battled. Organised too, was vocal throughout. Photo by Michael Steele/Getty Images.
4. Robin Koch
7 - Gave the ball away too many times in the first half, defended well enough before the break. Was much better after it, although Leeds were doing much more of the attacking. Photo by Laurence Griffiths/Getty Images.
