Manchester United fans have called on Casemiro to be sold for his role in Crystal Palace's opening goal.
Michael Olise opened the scoring against Erik ten Hag's men after a superb solo run before finishing past Andre Onana.
The Crystal Palace winger had picked up the ball midway through United's half and skipped past Casemiro, who fell to the ground after lunging in.
Olise, with time and space, continued to drive with the ball into the box and found the bottom corner.
And United fans have been left fuming on social media, with some calling on Casemiro to be sold after his disappoinintg season continued.
