Claudio Ranieri felt that Aboubakar dispute in the penalty box to decide who is in charge of the penalty taking was a sign of his disrespect acts toward him.
Kamara seized the ball and argued with the Serbia international before failing to find the net from 12 yards, seemingly condemning Fulham to a goalless draw with Huddersfield Town.
However, Mitrovic ran clear to score a dramatic 91st-minute winner and Ranieri’s fury with Kamara had not been tempered by full-time.
“I said to Aboubakar Kamara to leave the ball to Aleksandar Mitrovic, he is the man who shoots the penalties,” Ranieri told BBC Sport.
“It is unbelievable, [Kamara] did not respect me, the club, the team and the crowd. I spoke with him, it is not right. I wanted to kill him.
“That is normal when one man takes a ball, only because he scored the last penalty [against Manchester United]. It should be Mitrovic, that is it.”
Ranieri then giving his comment in the interview stated that “it is hard to reasoning with this man (Aboubakar) as he does not understand what you meant and he thought everything is fine in the pitch”.
“This is the very first time in my whole career as coach to see someone like this, it is absurd” Ranieri added.
Huddersfield boss David Wagner was frustrated with his side at both ends of the pitch as they fell to a seventh Premier League defeat of the month.
“It is hard to take,” he said. “If you see how we conceded, it makes it harder.
“We had a good opportunity for the counter and could not finish, then we could not close the gaps and conceded after Jonas Lossl made a great penalty save.
“This was a game with a lack of creativity form both sides. There were some shots and set-plays, but it was not a good game. We defended the counter well until the stoppage-time situation.”
