Georgios Samaras holds the key to Celtic's Champions League hopes according to Gianluigi Buffon.
The Bhoys host Juventus in the Round of 16 first leg on Tuesday and Bianconeri goalkeeper Buffon feels that Greece forward Samaras will have a big say in how the Glasgow giants perform.
"We have studied their previous Champions League games - and Samaras is a very big player for them," said Buffon.
"I know he is facing a fitness test to be ready for the game - but I think it is important for Celtic that he is fit.
"He seems to be their biggest threat in Europe and is where a lot of their goals come from."
