Journalist Massimiliano Nebuloni of “Sky” spoke about the demands of Walter Mazzarri on the market this summer. It was said that he would like a strong winger and a defender as a guarantee in case Vidic has physical problems. He would also like a midfielder who could alternate with Cambiasso and a striker who can improve the squad.

So basically one player from each position. Get Duncan back to fill in for Cambi, Mbaye for your winger, buy a defender (Schar, Dragovic), and use the rest of the money to get Dzeko. Most of our problems can be solved by bringing back our talented youngsters.
