Corriere dello Sport says Milan have agreed terms with investment firm DIS, which holds 45 per cent of Ganso's registration. The Rossoneri will now seek to finalise an agreement with Santos.
There's talk Milan will work with Internacional to buy Ganso in January.
The plan is for Inter to buy Ganso for €25 million - which is the fee set for any Brazilian club to sign the attacker. Then Milan will take the player off Inter's hands in the New Year.
Were they to buy Ganso directly from Santos, Milan would have to pay €50 million - which is his buyout clause for European clubs.
