Hernandez hit the winner in the second half to leave United five points clear of Fulham.

Luke Ayling picked up a yellow card on 10 minutes after he hacked down Pele following a Reading counter attack.
Patrick Bamford failed to get on the end of Jack Harrison’s cross, before Kalvin Phillips scuffed an effort at the keeper from just outside the box on 16 minutes.
It was the best United could muster up in the opening 25 minutes as the visitors continued to frustrate with organised defending.
George Puscas forced Kiko Casilla into a save with a long-range effort after Stuart Dallas was caught in possession on 26 minutes.
Phillips and Costa needed treatment for injuries as the first half began to lose rhythm, with Phillips subbed on 37 minutes after failing to run it off.

Cabral acrobatically beat away an Hernandez free-kick on 80 minutes before Bamford lashed a wild effort wide with four minutes to go, but Leeds were indebted to Casilla in the final minute as he spread his body well to keep out Puscas in stoppage time and secure the points.
