A statement read: "We are aware of the reported tragedy chanting during today’s FA Cup fixture between Manchester United and Liverpool, and we will be liaising with and supporting Greater Manchester Police.
"We strongly condemn any offensive, abusive and discriminatory chants in football stadiums, and we are determined to stamp this behaviour out. It is entirely unacceptable and can have a lasting and damaging impact on people and communities within our game. It must stop, and we support any club and their fans who try to eradicate this from the terraces.”
