Ferrari negotiated Anelka's move from Shanghai Shenhua to Juve in 2013 on a short-term loan and rates the deal among the best he's been involved in.
He told Tribalfootball.com: "Anelka was a great deal for both of the sides. The player was going to a great club again after the Chinese experience, Juventus was gaining a top player as a third or fourth choice."
