Marotta can't even sign the no names.
Having a look at his market performance over the last few seasons, which have mostly been failures in signing good players and showing zero ability to actually sell a player. it's enough for anyone to make a sudden decision in a moment of madness like Conte has done.
I think Marotta's market impotence and lack of investment by the club has been getting in Conte's nerves for too long and he just couldn't handle it any longer. Missing out on Sanchez would have angered him deeply, but the last straw which pushed him to make his rash decision may have been their inability to sign even someone like Iturbe. It would have made him lose all faith in our management and Marotta to sign any quality, even unproven quality.
