Former Premier League referee Dermot Gallagher says Casemiro was right to be sent off against Crystal Palace at the weekend and Andre Marriner couldn't have sent of Jordan Ayew.
Crystal Palace narrowly lost to Manchester United at Old Trafford after Bruno Fernandes and Marcus Rashford scored either side of half-time.
At 2-0, a fracas broke out which was initiated by United winger Antony and once it cleared up, referee Marriner was called to check with VAR with replays showing Casemiro with both hands around Will Hughes' neck.
