The fact people are rating the mercato at the beginning of the season makes me laugh. All of these so called "$#@!" signings could turn out better than a lot of you are predicting.
I prefer to rate how these transfers fare, you know, at the end of the season when I actually see how they play/fit into the team.
The mercato is rated when the mercato is over, it makes no sense to rate considering the sporting performances, there are far many more factors that determine this, which are irrelevant to the facts that were rellevant when the transfer decision was made.
For example, if a transfer director buys Messi for 20mil now, he ought to take full credit for the transfer, even if Messi brakes his leg right before the season starts and play no game at all...
The sporting performance might times depends and luck and esp the coach.
It is stupid to blame the transfer director for Coaches errors and vice versa.
Some fans who are ignorant of the new player's value can only rate the newcomer after the season, but players dont fall from the sky or magically appear from the abyss, the have a history, a previous team.
They have a certain value before they are acquired.
