Craig Gordon has warned his team-mates that they are playing for their place at Celtic.
Yesterday’s 2-0 defeat from Hibs came as a shock after it was assumed that the hoops had shaken off their early season struggles.
The performance at Easter Road was similar to those away to St Mirren and Kilmarnock earlier in the season and left Celtic trailing in third place.
With games in hand over the top two the hoops can recover top spot but it was the manner of yesterday’s defeat that set alarm bells ringing.
The transfer window opens in two weeks time with expectations high that Celtic will bring in players ready to go straight into the team.
“It’s up to the manager to decide what he wants in his squad and the positions we have to improve on,” Gordon told the Evening Times.
“The guys who are here have to step up and make sure they are in the manager’s plans, especially leading up to January.
“So it’s up to us to make sure our performances are good because at a club this big, if you’re performances are not up to scratch for a period of time then you can get replaced.
“We have to make sure we work hard enough to stay in the team and deliver the results the manager, the club and the fans want.”
Gordon added: “Do I expect him to be busy in January? I don’t know, I don’t know what his plans to bring players in are.
“I think he will want to do that but we will have to see what happens when that time comes.
“We will see who comes in and who goes. Then we have to start the second half of the season looking to go on a run again.
“There are a lot of games and we are going to have to use a lot of players. We’re going to have to try and have a strong end to the month now. There are still a lot of games and a lot of points to play for between now and then. We have to look to take as many as we possibly can to put us I a good place for the second half of the season.”
Celtic have to bounce back to form on Wednesday night when they host Motherwell.
Earlier this month the two clubs drew 1-1 at Fir Park with Stephen Robinson’s side going into the game on the back of ending St Johnston’s eight match unbeaten run.
