Juventus coach Massimiliano Allegri admits Miralem Pjanic and Gianluigi Buffon are doubts for their Champions League clash with Olympiakos.

The Bianconeri need a win in Greece to be sure of qualification for the Last 16.

“Higuain will play tomorrow, because he's fine physically and mentally," Allegri revealed in his pre-match Press conference.

“Tomorrow [Mario] Mandzukic will be available, there are two problems I'll have to evaluate tomorrow.

“One is Buffon and the other is Pjanic, so if they play, good, if not another two will play.

“Pjanic has muscular fatigue and Buffon has a calf problem, so I'll have to evaluate them tomorrow because I can't risk playing a player and then having them miss a load of games.

“If Gigi doesn't play then [Wojciech] Szczesny will play, so we're covered, but tomorrow is a lot more difficult and important than Napoli was.

“Tomorrow is the first objective of the season, there's time to recover in the league but tomorrow we don't have time to recover, because there will be no rematch after tomorrow.

“We need to win otherwise we risk going out, we can't wait for the match in Barcelona [against Sporting].

“It's a complicated game because we're coming off a really tough game against Napoli, and we already lost a first place once when we went to Sevilla with the wrong attitude.

“So tomorrow is a game where we have to be very attentive, very patient, because Champions League games aren't easy to win, especially away from home.

“So it's a complicated game for us tomorrow, a game we have to face with great respect, especially mentally, without thinking about what could happen in Barcelona."
