Manager Neil Lennon will be sacked by Celtic if they do not beat Kilmarnock on Sunday, according to Gabriel Agbonlahor.
Speaking exclusively to Football Insider correspondent Connor Whitley, the former Aston Villa and England striker claimed it is “a matter of time” before the Northern Irishman leaves Parkhead.
The Hoops have won just two of their last 14 games after they were held to a 1-1 draw with St. Johnstone on Sunday.
The club’s board released another statement after the game reiterating their support for Lennon and his backroom staff.
This site revealed last month the club will likely not sack the 49-year-old before the Old Firm clash in January.
The Hoops have put out a behind-the-scenes approach to former manager Martin O’Neill about a sensational return but he was not keen.
Asked by Football Insider how long Lennon can hang on for in Glasgow, Agbonlahor said: “It’s a matter of time now.
“They got a draw but I think if they had lost the game he probably would have gone.
“I feel like Celtic won’t just sack Neil Lennon if they haven’t got an adequate replacement. You won’t just sack someone if you haven’t got anyone to come in.
“They’re probably waiting until the next time they lose to a team they should be winning against and maybe then he’ll be gone.
“It’s a shame to see because I like Neil Lennon, he’s a passionate manager who loves Celtic and it’ll be a shame for him to go.”
Celtic are now 12 points behind league leaders Rangers, although they have two games in hand over their Glasgow rivals.
They play Lille in their final Europa League group game on Thursday night but are unable to progress to the knock out stages.
