Milan are set to introduce a new code of ethics with fines for taking off shirts to celebrate goals and late nights.
According to the newspapers, the Rossoneri are planning to impose strict rules on the locker room to minimise bad behaviour.
Heavy fines will be introduced for any player who takes off their jersey to celebrate a goal, especially as this leads to an automatic yellow card on the pitch.
This has caused problems in the past, as Antonio Cassano was famously sent off in the derby with Inter two years ago after he was booked for whipping off his shirt.
There will also be a fine for any player breaking curfew, as late nights out will be barred ahead of games.
