Andrea Agnelli says Juventus will make changes at the end of the season leading to doubts about the future of Gigi Del Neri and several players.
The Juventus President is unhappy after back-to-back defeats to Lecce and Bologna meant his team risk not qualifying for next year's Champions League.
Juventus currently lie seventh in Serie A and are worse off than at this stage last season.
"The unity of the group is intact," Agnelli said. "We know very well that we are going through a moment of difficulty.
"We are perfectly aware of the changes that need to be made next summer, but the story that we are writing won't change.
"Moments of dialogue exist in which it's more or less intense according to the results. This is a moment in which it is more intense.
"But the group is united and compact. I am convinced that it has potential and that it wants to show it."
