00:00It had been a summer of change at West Ham, Julen Lopetegui in charge and a raft of new signings,
00:06but it would be Aston Villa's new man who would make an instant impact.
00:18No side in Premier League history has had more debutante score than Villa.
00:22The visitors were dangerous, how's this touch from Leon Bailey?
00:31John McGinn was next to go close.
00:38Before all that good work was undone thanks to a very soft penalty call
00:42for a collision between Matty Cash and Thomas Socek.
00:45Lukasz Pichetta to do the honours.
00:49Very poorly done.
00:51And on an afternoon of Aston Villa dominance, West Ham have parity.
00:57Come the second half and both sides refresh their attack.
01:00John Duran on for Villa, while the Hammers welcome new signing Nicholas Falkrug.
01:05Only one of those would make an impact and it would be a case of what could have been for the hosts.
01:10Mattson coming forward, that's a great touch, Duran to Juan Villa.
01:14Well over the course of the summer it looked as though he might become a West Ham player.
01:19Instead he's breaking West Ham hearts.
01:22Socek spurned a glorious chance to level things up at the death.
01:26Lopetegui's reign starting with defeat.
