Juventus coach Massimiliano Allegri says Arturo Vidal will play against Champions League opponents Olympiakos.
Vidal has missed the past two games for Juve.
Allegri said: "I have several choices still to make. I can be sure of the four defenders, but that doesn't mean I will play with four at the back, plus Tevez and Vidal.
"Arturo is doing better and the last few days training in Turin improved his fitness levels. Tomorrow I hope to see an excellent Vidal, albeit not at 100 per cent for the full 90 minutes, but hopefully in good shape."
