1977–78 West Ham United F.C. season

Despite winning six of their last nine League matches, they paid the price for a terrible start to the season that had seen them win just one of their first twelve games, and were relegated when they lost their last match to Liverpool and Wolverhampton Wanderers beat Aston Villa.
