Manager of the Mexico national football team, Miguel Herrera has some interesting demands for his players in order to win this the World Cup.

Last month, Herrera reportedly told Reforma newspaper that he wants his players to abstain from sex while they are in Brazil for the World Cup.

"I am thinking about soccer and I hope that the boys are thinking about soccer because nobody has died from practicing abstinence for 40 days," Herrera later told NBC News.

Herrera's reasoning behind his odd request dates back to the beliefs of the ancient Greeks, reported ABC News via The Associated Press.

The Ancient Greeks reportedly believed that safeguarding a man's sperm was important for spurring aggression needed to perform well in the arena.

So will the players oblige to Herrera's orders?

Maybe.

Though it may sound strange to many, there are other teams around the world who refrain from having sex before a big game.

According to NBC, Ghana's team was banned from having sex and beat the U.S. during a game.

Coincidence? Perhaps.

However, England's players implemented the same policy but got disappointing results -- they lost.

So perhaps, based off of the mixed results, players can practice the policy at their own discretion.

Much like the results in the past, players are still iffy about practicing "no sex" before a game.

"I have had sex several times before some games. It helps you concentrate ... I have noticed that in some games that I played better because I had sex before them," 2002 World Cup Winner, Rinaldo said to Brazilian TV.

On the opposite end of the spectrum, Champions League winner told Cosmopolitan UK, "I'm a good boy -- no sex the day before a match. If I had to choose which was better, football or sex, I'd say football. It's 90 minutes of pure pleasure and I can't always say that about sex. But it depends on the fixture and the score."
