That's simply an INSANE offer. I really hope it's not true. Does not make ANY sense.
In a way, it makes perfect sense. Let me indulge in some speculation, more like joining the dots:
Kia Joorabchian is the guy who got all those stars like Ramires and Teixiera for Jiangsu Suning. He became the football advisor to Zhang Jindong even before Suning bought Inter. This is fact.
Once Suning bought Inter, looks like there was an obvious power struggle. Kia was advising the owners on transfers, and his targets were very different from the ones Mancini wanted to focus on. Thohir had given the manager the control of transfers, and Mancini was not ready to give away that control. Ausilio backed Mancini, perhaps because he perceived a threat to his job by the likes of Kia Joorabchian.
We know what happened next. Mancini lost the power struggle, and was offered a contract extension without any say in transfers. He refused and left, and was replaced by one of Kia's own men (guess who represents Frank De Boer?). Now there is an alignment in the transfer market between Kia and De Boer, though its unclear who is more in-charge. My fear is that since Kia is the closest to the owners, he is getting his way - this crazy Joao Mario bid seems to suggest that. Guess who Joao Mario's agent is? Who will get a cut of the crazy transfer fee? Its Kia, of course. I don't trust "greedy super-agents" like Kia, their self interests are rarely aligned with the clubs they represent. You have to work with them at this level and keep them in good terms, but never let them dictate the club's strategy - they should NEVER have more power than the Sporting Director or the Coach. That will end in disaster for the club (and great business for the agent).
So is it all bad? No, there are some silver linings:
1. Ausilio almost quit because of all this, but thankfully he has been persuaded to stay with an extended contract. Hopefully this means that Zhang Jindong (as a clever businessman) wants a power counter balance to Kia in Ausilio.
2. Frank De Boer sounds like his own man. A lot depends on whether he has the balls to demand the players he wants, and whether he is stubborn enough like his predecessor to get what he needs.
