Neil Lennon is sweating over the availability of two key players ahead of the first leg of Celtic's Champions League last-16 clash against Juventus at Parkhead this evening.
Forward Georgios Samaras is battling to recover from a hamstring injury while defender Efe Ambrose played for Nigeria in their 1-0 African Nations Cup final win over Burkina Faso and arrived back in Glasgow this morning.
Left-back Emilio Izaguirre has recovered from a knee injury while winger James Forrest is fit again following a hamstring problem.
The Hoops boss said: "It is as you were with Samaras, we will make a decision on him before the game.
"Izaguirre trained today and has joined the squad and Forrest is fit and Ambrose, we expect to arrive tomorrow morning.
"We will see what condition he is in and if he is okay, 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 okay.
"If not, then I have a very strong squad and we will have him fit for the second leg."
