In case Sam Allardyce wasn't entirely aware of what the challenge ahead of him looked like, this defeat would have provided a significant reality check. While Crystal Palace started the game well, a failure to take chances was then punished by West Ham's ability to capitalise on Palace's defensive errors. Allardyce's side look incapable of keeping a clean sheet.
Positives
It really is difficult to find any from this performance -- the result might however highlight what the club need to do in terms of recruitment because key players, in midfield and defence mainly, are just not doing their jobs.
