Catania players Armando Pantanelli, Mattia Biso and Gianluca Falsini have launched legal action against the club.
The trio are transfer-listed and are launching their action over claims of bullying and discrimination.
"There is no case of bullying," assured general manager Pietro Lo Monaco. "The three players are training regularly on our field with our fitness coach.
"Despite the fact these three are no longer part of our plans for the next season, they are still being paid handsomely for doing absolutely nothing."
