Manchester United's goalless draw with Southampton at Old Trafford on Sunday afternoon was overshadowed by Casemiro's first-half dismissal.
The Brazilian, who has been exceptional since joining United from Real Madrid last summer, was sent off with 34 minutes on the clock following a VAR review. The midfielder was initially booked for a heavy challenge on Saints midfielder Carlos Alcaraz by referee Anthony Taylor, only for VAR to intervene and send Taylor to the pitchside monitor to review the decision.
The experienced Premier League referee then decided to brandish a red card, marking Casemiro's second dismissal in just three league appearances. He was previously sent off during last month's win over Crystal Palace.
