German national team players will have to observe a compulsory celibacy during the 2018 World Cup tournament in Russia.

The head coach of Germany, Joachim Low, has banned the players from having sex and using social media during the 2018 World Cup tournament in Russia.

But the defending champions are allowed to have a glass of wine or a beer before bed.

According to La Gazetta dello Sport, players will, on approval, be able to see their wives, children and girlfriends in the build-up to Russia 2018. Not during the competition itself, though.

But while nights of passion are almost out of the question it is not forbidden to take alcohol before going to sleep. So long as drinking is kept within reasonable bounds, of course.

Low has laid out his dos and don'ts quite clearly, insisting: "The team is more important than the ego."

"The guys know our behaviour guidelines well, they know what our ambitions are and what our tasks are: no one can become a world champion, we are all pieces of a puzzle."

Low added: "Everyone must be aware of their role within the team. The personal ego must be appeased."

The Germany national team who are in Group F, will face Sweden, Mexico and South Korea.
