There may be a new manager in the home dugout of the London Stadium but old problems remain.
West Ham ended last season under David Moyes on a run of 18 league games without a clean sheet.
That is now 19 after Julen Lopetegui's Hammers conceded after just three minutes and 40 seconds, with Villa's Amadou Onana allowed a free header from two yards out.
Aston Villa's new defender Amadou Onana scored on his debut after just four minutes
Lucas Paqueta levelled the scoring from the spot for West Ham
West Ham's defence was cut open far too easily and had Villa been more clinical the scoreline could have been more damning.
