Well, his father is deeply implicated, so there is a complicated relationship there. Most elite footballers are simply not ready for the consequences of fame and wealth...the examples are so obvious and numerous that they needn't be mentioned here. And for those less fortunate than Messi, what seems a fortune can vanish overnight and retirement from the game comes with the terrifying need for a poorly-educated, physically scarred athlete to shed his "friends" of the good times and pursue a real career. A fair few don't make it.
But I agree that, whatever the cause and however much Messi himself is or is not personally involved, he remains responsible and it is his legacy that will suffer for the actions of the people around him.
With that being said, the behavior of Barca and even Real in all this should not be ignored. These are not just people - these are big institutions behaving in a startlingly reckless fashion. They believe the normal rules simply do not apply to them and, thus far, they have gotten away with it. At some point I hope there will be a reckoning.
Oh, agree absolutely; the father is deeply implicated, but I don't really buy that Messi is not.
And agree, too, on the culpability of clubs such as Barca and Real.
But as for the old "if only the Tsar knew about it, he should do something about it" - history has demonstrated all too clearly that - most of the time - the Tsar did know about it and had no intention of doing anything whatsoever about it.
