Erik ten Hag laid into his Manchester United players after they conceded an “unacceptable” late goal to end their 100 per cent record under him.
David De Ge was left rooted to his line as Aston Villa's Calum Chambers headed past him with the last action of the game at Perth's Optus Stadium.
United, who flew back home straight after the game, were looking to make it four straight wins under ten Hag, who was in no mood to spare his players from his anger at their loss of focus.
