Erik ten Hag rebuked Manchester United players for letting their standards drop after their 4-2 friendly defeat by Cadiz.
United were 2-0 down inside 13 minutes at the Estadio Nuevo Mirandilla and, although they drew level through Anthony Martial's penalty and Kobbie Mainoo's deflected strike either side of half-time, Cadiz won comfortably.
Ten Hag was unhappy with the first-half performance and changed the entire outfield team for the second, introducing 10 academy players.
