Despite doing some horrible deals like 12M for Martinez, 15M Bonucci, 18M Matri, etc, Marotta did a lot of very good moves and completely rebuilt the squad in 2 years. He had money for it, but in the end he succeeded at it - we are younger and the best in Italy.
He did a good job at that. But honestly, he doesn't look like being the man who is going to make Juve relevant in Europe again. Lacks ambition, daring. Agnelli should think about that.
