AC Milan vice-president Adriano Galliani admits they must sell to buy.
Galliani has stated that his club won't be able to buy new players until they reduce their squad.
"We have 30, 32 players right now," he told RMC. "We will firstly sell and then, when the squad has been reduced, we will buy.
"We have some players who want to go, just a very few, and others who we wanted to sell but who didn't accept new destinations because they are happy at Milan."
