The Frenchman was strongly criticised by his manager Claudio Ranieri for disobeying orders to hand over penalty duties to Aleksandar Mitrovic.
“It is unbelievable, he did not respect me, the club, the team and crowd. I spoke with him, it is not right. I want to kill him,” said Ranieri, despite Mitrovic’s stoppage time winner in a 1-0 victory for the Premier League strugglers.
However, Fulham have promised to support Kamara after he was abused online.
“The club will provide all necessary support to Aboubakar and will take the strongest possible action against those identified and responsible for these posts,” a club spokesman said in a statement.
