The article says "three bianconeri" meaning DC, Martinez, and Quagliarella will start training. It mentions Sissoko too but on the bottom of the page...
But it is a mental issue. True Sissoko will never be a great passer and Amauri will never be prolific but this is no excuse for the downright awful form of the two in almost every department. There is clearly more going on.
I'm sorry to say it but he no longer adds anything to this team. Its not just about him giving up the odd pass anymore.
He really is playing terribly these days.
