Inter Milan president Massimo Moratti says a big name signing is on the agenda.
Moratti urged the Nerazzurri support to be patient in the summer market.
"A top player could arrive here, but it depends on the first days of Mazzarri. We're only at the start of July, there's plenty of time between now and the end of August.
"The most interesting deals often come about towards the end of the market.
"Anyone leaving? They're all not for sale because I want Mazzarri to take a good look at them first and figure out what works best for him."
