The money in men's football is crazy.
Due to the popularity of the sport, the world's best players get paid ridiculous amounts of money.
Even those who play in League Two, the fourth tier of English football, receive a comfortable wage.
But the same can't be said for women's football.
The women's game is nowhere near as popular as the men's game. As a result, they don't get anywhere near as much money as men.
And a latest report from France Football magazine shows the massive pay-gap between men and women's football.
France Football calculated the highest paid players in world football when you take into account salary, advertising revenue and bonuses.
Carli Lloyd has the honour of being the highest-paid woman in the world.
However, she earns 'just' €480,000-per-year.
The American international, who plays for Sky Blue FC and has featured in 294 games for her country, earns €40k-per-month, €9.2k-per-week and €1.3k-per-day.
Obviously that is still a hefty amount of money, but that's nothing in comparison to Messi's wage.
To put this all into perspective, it takes Messi just over 31 hours what it takes Lloyd to earn in a year.
Wow. The difference between the two players' earnings is staggering.
Women have been calling for equal pay with the male's game for many, many years.
Megan Rapinoe is one such advocate of the idea, who recently said that women should 'fight like hell' to achieve parity.
"Don't settle for anything less, go for equal, go for more, don't accept any of these sort of antiquated and BS answers," she said in November in a message to women about the fight for equal pay, per the BBC.
"Especially when it comes to sport there's been such a lack of investment for such a long period of time, so any direct comparison to the men's sports or the men's leagues is just wholly unfair.
"Until we have equal investment and over investment really, because we've been so underserved for so long, we're not gonna have any sort of meaningful conversation about compensation and revenues and TV viewership.
"I know it's frustrating and hard - at times you feel like you're banging your head against a wall - but we're sort of in it anyways.
"It's a fact of life for us so we might as well fight like hell."
