There’s some really grim stuff that footballers get up to.
A lot of them don’t have proper adult relationships with women because they’re out of school at a young age, and spending all their days almost exclusively with other male teenagers coached by ex-footballer men.
Then if they go pro they’re told that “all women are gold diggers” from other pros which is true in a lot of cases with ballers but it’s not hard to imagine that mentally warps a lot of these guys minds and gives them messed up views on relationships with the other sex.
They start going round thinking every girl is for the streets and it carries over into their dating lives as well. I know a few lower level footballers and girls who’ve dated them and almost universally they’re all pretty possessive and immature.
Most of us here even if you’re single have probably been raised by women, went to school with other girls and female teachers, then worked with them in our adult life. They’ve not really had that in their development.
Add to that that a lot of guys will act up and frequently get on in sex parties and whatnot.
It's a common anecdote here in brasil that some managers take their players out to the red light district as a reward. The fact that only a few footballer openly come out as gay is also another telling aspect of how people behave inside the game.
Hell, just look at Benzema and Valbuena.
