Luftstalag why don't you calm down a little bit, seems like you're attacking other users that just want to discuss the issue at hand. Messi and his father are not innocent as we have seen in the previous tax case. Yes he is the greatest player, doesn't make him the greatest citizen in the world. Offshore companies are daily business in wealth management, as soon as you are a UHNWI, i.e. ULTRA HIGH NET WORTH INDIVIDUAL, there are several ways to "optimize" taxes and invest money. Some countries have tougher tax regulations than others (e.g. Switzerland, Luxembourg and other havens have are much more relaxed ones than France, Germany etc.). The panama papers may be criticized (e.g. Putin's name is not once recorded in any of the documents but the news outlets present it as if Putin was the guy behind all the things, there are no US names, there are no German names, the news outlets write more carefully about US/German issues while writing heavily biased about Putin). However, Messi has a court case regarding his previous tax issue. If something like this comes up again, it is totally normal for anyone to assume there might be some wrong doings involved again. Even if he is not guilty this time, it is just normal.
Messi is not the first nor the last to be involved in these cases. Again, even if he is a god on the pitch, that doesn't make him a saint when it comes to money and taxes.
