The moment he arrived [right after we finished 7th with a negative GD and we missed out on the CL money], Marotta faced the challenge of deciding what to do with the aging (super)stars. Among the 22 players who had played the most minutes before he arrived, 14 were 30+ (Camoranesi, Del Piero, Trezeguet, Grosso, Cannavaro, Iaquinta, Legrottaglie, Zebina, Amauri, Buffon, Poulsen, Salihamidzic, Grygera, Manninger). Most of them were, at the time, on very high wages, and, except for Buffon, all of them were (way) past their prime at the highest level.
Additionally, Diego and Felipe Melo were on high wages, and a decision needed to be made whether to build the team around them (and the season 09/10 showed that they aren't that good to deserve such a privilege), or let them go.
Caceres was on loan and returned to Spain, while Candreva was also on loan and returned to Udinese.
What remained after all this were: Chiellini, Marchisio, Sissoko, and De Ceglie.
This was an incredibly tough position for someone to start their Juve career as a director.
