Organisers are trying to make this the first tobacco-free World Cup, with smoking not allowed in any of the stadiums.
Fifa has also written to all 32 coaches, asking them to refrain from smoking on the touchline - although it admits it can't do anything to stop them.
Good job Klaus Toppmoller isn't in charge of a national team yet.
No sex please
The Italian squad have had a sex ban imposed on them by coach Giovanni Trapattoni, in case it distracts them from the job in hand.
Trapattoni said: "I've been away training for big matches myself in the past and I know what goes on.
"I know what footballers think about, but there have to be rules and regulations, even when it comes to a matter as delicate as this."
Trapattoni's statement prompted the headline: "No Sex Please, We're Italian" - written in English - in the Corriere della Sera newspaper.
He responded by saying the players would have to "make up for lost time when they get back to Italy".
In other words, lock up your signorinas.
