BBC Sport - Celtic v Juventus Champions League Coverage: BBC Sport website live text, BBC Radio Scotland & BBC Radio 5 live Celtic's major doubts Georgios Samaras and Efe Ambrose will be given every chance to be available. Samaras is battling to recover from a hamstring injury. Ambrose played for Nigeria in their Africa Cup of Nations final win over Burkina Faso on Sunday and will not be back in Glasgow until Tuesday morning. Emilio Izaguirre has recovered from a knee injury while winger James Forrest is fit again after a hamstring problem. Celtic manager Neil Lennon: "It is as you were with Samaras, we will make a decision on him on Tuesday. Izaguirre trained today and has joined the squad and Forrest is fit and Ambrose, we expect to arrive on Tuesday morning. We will see what condition he is in and if he is OK, we will have him in the squad. We will give Georgios as much time as is needed. He has been doing pretty aggressive rehabilitation work and we are hopeful he will be OK. If not, then I have a very strong squad and we will have him fit for the second leg.
