Islam Slimani eased any growing relegation pressure at Leicester as the champions held on to beat West Ham 1-0.
The striker's header sent the Foxes six points clear of the Premier League bottom three with just a second top-flight win since October.
Michail Antonio hit the bar for the Hammers who, despite dominating the second half, failed to find a way through to end their run of three straight wins.
The Foxes finished a year where they won a shock title on a high after a poor first half to the season which has seen them drift dangerously close to the drop zone.
