Championship leaders Leicester City wore down bottom side Rotherham United to go six points clear at the top at Christmas.
The Foxes took full advantage of a 4-0 defeat for closest challengers Ipswich at Leeds in the lunchtime kick-off to stretch their lead and maintain their 13-point cushion in the automatic promotion race.
After being frustrated in the first half by the resilient Millers, Patson Daka steered home the opener on the hour after Viktor Johansson had saved from Wesley Faes.
Daka soon added a second from the penalty spot after the Zambian forward had been taken out by Johansson when clean through, and Cesare Casadei headed in Ricardo Pereira's cross as Rotherham subsided.
