Crystal Palace defender Joachim Andersen says he has received 300-400 abusive messages on Instagram after he was involved in an incident that saw Liverpool's Darwin Nunez sent off.
Andersen posted examples of the abuse, some of which included death threats.
He has called on Instagram and the Premier League to act.
"Got maybe 3-400 of these messages last night," the 26-year-old said. "I understand you support a team but have some respect and stop act tough online."
He added: "Hope Instagram and the Premier League do something about this."
Palace are set to speak to Andersen to offer support.
