Sport says Massara is now back in Italy having done his job in Barcelona on Friday night. Massara met with Todibo and said the conversation was "positive".
Meanwhile, Sky Italia says Milan have struck an agreement in principle with the young French centre-back, meaning they now just have to reach a deal with Barcelona to push a January move through.
With the player on side, Milan hope to close a loan until the summer with an option to buy. To make sure they get their man, the Italian side have not ruled out including a buyback option for Barcelona in the future.
Negotiations will continue between the two clubs in search of a satisfactory solution for all three parties.
