When a player is suspended, the whole team is informed and when a club has been confronted with it many times in the past, they have an intense way of controlling it all. And everyone knows the story of juventus and the scandal and the relegation to Serie B, this fear mybe still exists in the management. In the last season the point deduction, 2x, and now it continues with the players. It is like being unwell, which leads in many cases to a turbulence, so no extreme good performances as a team. How would you feel if you were supended from your dream of being a soccer player, not good, and mybe the team also.
Not everything can depend on the team, if the management does some kind of financial fraud, then the players may not even be informed about it, but in the end everyone suffers (when the team was sent to Serie B).
Also, the team cannot control players who may use doping, of their own free will or with any medications. In this case, the player, and not the entire team, will be responsible for his actions.
Juventus is playing better this season and I even hoped that they would be able to compete for the Scudetto, but now Alegre is involved in a scandal with bets, and he faces disqualification for 3 years. This looks like a lack of discipline in the team and not due to some kind of bad luck.
