The agent Fabio Parisi analyzed Mazzarris will to have less players in the squad:

“Mazzarri doesn’t see any problem with the persons, but with the squad. He doesn’t want to have a squad that is to big during a season where Inter won’t play in Europe, and they will practice 5 days for one game. Then he does the right thing to ask for players to be sold.”
