From a Falcao-having point of view, he's the worst.
Before anything, im not a marotta fanboy, and i have to say that yes, he has been unable to land us a top striker. thats for sure.
But to blame us fans, and to blame everything on him, is just being naive. At this point u must know that we are not a filthy rich team, and a top striker will demand wages that can be comparable to the wages of 5 or 6 of our players put together, not to mention the price of said striker.
Think about the huge deficits we have had since calciopoli and the huge money influx other teams have received thanks to oil barons and any kind of millionaries who spend money just for the sake of it.
Also the italian league is in not the best of situations.
I really dont understand how can u blame marotta alone, when the reasons are definitely more complex.
