Juventus great Claudio Gentile believes the players could be affected by the club's financial investigation.
Juve's accounting practices are being probed by authorities.
Gentile told Radio Rai: "I don't know that. When I was at Juve there were no such problems.
"Surely, given that the team is not doing well, these extra-football things can also enter the field.
"It is up to (Max) Allegri to be able to reach the goal in fourth place. Juve without Champions League football would be an incredible failure."
