David Moyes admitted that his West Ham United side have «been off the boil a little» ahead of Sunday's contest but they completely imploded while conceding four goals in a ruinous first half against Arsenal.
West Ham had already beaten Arsenal twice this season, dutifully frustrating the Gunners with a compact and concrete rearguard. However, Arsenal's finishing — or lack thereof — played its role in the Premier League and Carabao Cup reversals.
