Celtic manager Neil Lennon has vowed to name and shame certain players after their 0-0 draw with Hibernian on Saturday.
The result has left the Hoops 12 points behind rivals Rangers, who lead the SPL table.
Lennon says that he is prepared to out those players that he believes are not putting in as much effort as he would like.
"A few have been consistent like Ki [Sung-Yueng] and Joe Ledley. But there are others who are happy to go along, riding on their backs," he said.
"I have to speak to them and out them, basically.
"I am really angry. They let the game drift away from them and that is not acceptable."
Celtic next host French side Rennes in a Europa League group stage fixture on Thursday.
