I don't know about the other DS's in Italy, but this guy has to be among the more clueless ones out there. He's like the Borriello of DS's.
Beware of the 'grass is greener' school of thought. There are few DS' in Italy who have experience of working at such a club, so it's just the same gamble. 'They must be better'. No, they could certainly be worse.
Marotta's position remains the same now as it did in September, October, November and will through to May, in the summer he'll surely have CL football to work with and that demands quality. In KO football you need it even more.
Not signing big players for big money and wages doesn't bother one bit for this season. What bothers me is the number of signings, when I think resources and focus could have been channeled better. I'm not talking about not signing Matri, Pepe, Padoin and Elia means Agüero, because football simply does not work like that, rather players in between those two levels, so the grade in quality doesn't have to make so big a leap.
