Yesterday, the Hoops could not even trouble the scorers against Hibernian with a 0-0 draw the end result at Parkhead, leaving the Glasgow 12 points behind ‘Gers in third position.
Celtic boss Neil Lennon had seen an improvement from his side in last week’s Europa League draw with Rennes in France, last weekend’s 2-1 home win over Aberdeen and the 4-1 League Cup victory over Hibs midweek but was disappointed when they could not break down the opposing defence on Saturday.
The home side were wasteful, infuriating Lennon who has vowed to make changes in a bid to freshen things up in his squad which has fallen behind in their quest to halt Rangers’ run of three straight SPL titles.
"I am really angry, they let the game drift away from them and that is not acceptable,” he said.
"I would like to make changes but the way the squad is stretched it is difficult to do that.
"There are a few who have been consistent like Ki and Joe Ledley but there are others at the minute who are happy to go along, riding on their backs and not really making the contribution that I want from them.
"I have to speak to them and out them, basically.
"I am not happy with some of them at the minute.
"I don't think they are giving enough in terms of the quality of their play or effort and I will speak to them individually and tell them what I think and I am looking for a response from them.
"But you ask them questions at times and you don't get answers."
