The Christmas period is one of the busiest times of the year for football clubs and three big Hammers fixtures in December have now been moved.
The Hammers' clash with Chelsea on 1 December at the Boleyn Ground has been moved to an earlier time of 12.45pm.
The clash against Liverpool one week later has also been changed. The visit of Brendan Rogers' side has moved to Sunday 9 December 2012 and will kick-off at 4pm.
The third and final change takes place on Sunday 16 December 2012 as West Ham United travel to the Hawthorns to take on West Bromwich Albion. Just like Liverpool it will kick-off at 4pm.
