Casemiro has been roasted on Twitter by football fans after a video emerged online of him being 'sat down' by Jack Grealish during Manchester City's 6-3 demolition of Manchester United on Sunday.
The defensive midfielder, who arrived at Carrington from Real Madrid this summer for a £70million fee, came on as a substitute just on the hour mark.
But the Brazilian, who is yet to start a Premier League game this season, was given a tough introduction to the Manchester derby by Jack Grealish, who embarrassed the 30-year-old with a 'rude' piece of skill that sent the United player falling backwards on his heels.
