To fight for the Scudetto until the end, AC Milan needs to invest in quality profiles. Important players must arrive to help out the squad of Stefano Pioli.
Technical area director of the Rossoneri club, Paolo Maldini, did say in a recent interview that no mercato moves are planned. But, there will still be some operations, despite his words, write Milannews.it in their editorial.

The attack needs an improvement and that is why the club is targeting River Plate's young talent Julian Alvarez. However, it will be hard to sign him because many other important European clubs are on him. AC Milan still want him and have sent their scouts to Argentina to keep an eye on him.
The midfielder position will also need to be strengthened, writes the same source. Franck Kessié and Ismael Bennacer will leave in January for the African Cup of Nations and the club may need to go into the market to get someone to cover for them. AC Milan are enjoying a good relationship with agent Jorge Mendes who represents Renato Sanches of Lille, and in a few weeks, "there will be a more in-depth evaluation from the economic point of view."
Renato Sanches is an appreciated profile for the club management, but for now, it seems like it is more of an operation for the summer, unless a good offer comes in for Franck Kessié.
