I don't get the point of not taking a break though, are they like some kind of robots that they can afford to not take a break and that even if they do this all year long, they wouldn't experience any kind of mental breakdown? Football players are pretty much humans like the fans so I don't agree about not taking breaks, even if they make a lot of money, I don't think that no money can provide them the care that's equal to taking a break.
Another interesting question is this, as a father would you force it on your child to also fan the same club you're a fan to, or you will allow him be himself to fan any club of his choice even if it's your most rival club of all times.
Probably the most pathetic and stupid thing that you can do to your kid, to have them continue what you're dreaming of as if that's how you should do things as a parent, unless you're a really bad parent that would want to raise a kid that doesn't love you and will grow to resent you then yes you could force them to like the fan club that you're a fan of, if they show interest then it's good to at least be that way but forcing them when they don't want to is not the way to go. It also is a good idea to allow them to be a fan of other clubs or a rival one at that, it raises the kid's confidence and the sense of being competitive is instilled to the kid although too much competitiveness is a bad thing too.
