Celtic boss Neil Lennon admits they could lose goalkeeper Fraser Forster back to Newcastle United in January.
Forster may be recalled by Newcastle in January after first-choice Steve Harper was injured.
Lennon said: "I'm very happy with the three goalkeepers I have at the moment. Fraser has done very well since he's gone in but with Steve Harper's injury, they might want him back.
"If they want him back in January, there is very little we could do about it and we'll have to look at our options again."
