Keeper backed by colleague
Goalkeeper Dorus de Vries has been backed by team-mate Kristoffer Ajer ahead of coming back into the side for the injured Craig Gordon.
The 37-year-old Dutchman has managed only seven appearances since moving to Parkhead in August 2016.
However, regular custodian Gordon will now be sidelined for around three months with the ankle injury collected during the weekend victory against Hibernian.
"I'm just looking forward to playing with him for the next games," Ajer told BBC Scotland. "Craig is an experienced guy, he knows that football can be harsh sometimes, but he will recover as good as possible and be back stronger.
"Dorus came in for the second half against Hibs and he did fantastic with the ball and he's a shot stopper as well, so he's a great goalkeeper with a lot of experience."
