The Independent has more details on England’s new, wide-ranging code of conduct that it expects England players of all levels to obey. The code was presented to the senior national team last
The section on standards of conduct forbids “violence, abuse and discrimination (of all kinds),” and “use of drugs without the doctor’s permission.” Alcohol use is subject to the discretion of the coach. According to the code, ordering room service in team hotels is forbidden. Video games can be played “for a sensible amount of time” and use of mobile phones in team areas is at the discretion of the manager. They are also told not to react to “verbal provocation from the press or fans” – "however hard it is" – and to wear England branded clothes at all times, "apart from footwear," unless given permission otherwise.
England players are also forbidden from criticizing teammates, staff, referees or officials on Twitter or Facebook, and they may not use Twitter at all the day before or the day of a match. They must also never talk about team selections or tactics to anyone outside of the circle of the squad. Betting of all kinds is also forbidden.
Interestingly enough, the code encourages players to conduct interviews with the media, and to acknowledge supporters at the end of every game. However, no “exclusive media columns or blogs” are allowed.
