0/10 for the idiots that thought it was a good idea to sign him when your operating revenue is not even amongst the top 10 clubs in the world. Marotta left for a reason.
A solid 6.5/10 for his performances on the field. Great first season, really good second season and an average final season. The return on investment was pretty mediocre overall given that we were paying him €60M gross a year.
I will remember his signing more for the shock value and all the hype and euphoria it generated and less for the performances on the pitch. The day his signing was announced was a truly memorable day.
Based on value and impact, Tevez and Dybala for me are the two best strikers we've signed post Calciopoli.
