Better to let opposing teams think certain players might no be available, then oops, here they are starting. No real advantage to be gained by giving return dates.
That's the sort of arms race that turns football (well, what's left of it, anyway) from a sport into high geopolitics, though. The clubs would be delighted with that, no doubt - the less information about their internal processes they can give out to the world, the better, and they can get down to competing against their rivals as nations compete with one another, all realist power politics and misinformation maneuvers. Ultimately, the only people who suffer from that approach are the powerless fans, who are left with little to do but obediently come to the games, cheer and then go home, because you're b*ggered if you want to know anything else about your club beyond that it plays at a certain stadium, at a certain time.
It's why I'm utterly baffled by people like
@Whiffler taking the mick out of fans who want to know about what goes on at the club - believe me, if they could get away with it, they'd be delighted with running like actual corporations, with all the secrecy and business-consumer relationships that entails. At that stage, you're really not watching a sport anymore, you're just watching quarterly reports being compiled every weekend. If that's okay by you, fine - but it isn't exactly unreasonable that fans feel more than a little uneasy at that prospect. And, incidentally, if you're fine with that, then, logically, you should also be perfectly happy with people booing the team, leaving early, not making any noise or demanding refunds after poor performances - after all, it's a business transaction, and the customers (formerly supporters) are simply exercising their right to express their dissatisfaction at the poor product offered by the club.
Forget about this. I raised the same question a few weeks back and was absolutely slaughtered for it by just about everyone who posts here.
Didn't know about that, but if so, that's a damn shame, and reflects a bit poorly on what we apparently seem to think supporting a club entails.
