Casemiro's mindless red card turned a routine victory into a nail-biting finale as Man Utd held on to beat Crystal Palace 2-1 at Old Trafford.
Before the Brazilian was dismissed by a VAR review for putting his hands around Will Hughes' neck, United appeared to be in cruise control and led 2-0 through an early Bruno Fernandes penalty and Marcus Rashford's smart finish.
But after they were reduced to 10 men and Jeffrey Schlupp's snapshot gave Palace hope of a comeback, they almost threw away victory in the final minutes.
Jean-Philippe Mateta and Eberiche Eze both went close to stretching Palace's unbeaten record against United to three games, but United weathered the storm to limp over the line to a 13th consecutive home victory.
