Real Mallorca have reportedly handed their players a list of rules, which includes a ban on piercings, necklaces and 'extravagant' haircuts.
It is believed that from this weekend, the first team will not be allowed to wear hats on the team bus or in the changing rooms, while toilet paper must not be stolen.
According to IB3 Radio, manager Albert Ferrer, who spent five years of his playing career at Chelsea, has implemented the rules, which also include an 11pm curfew that can be extended to 1am.
The club currently play in the Segunda Division in Spain.
