There are reports that Milan will sign Andrea Lazzari from Cagliari if Ronaldinho leaves at the end of the season.
The Brazil international playmaker's contract is due to expire in June and it remains unclear whether Milan will extend it.
Ronaldinho has lost his place in the starting XI and given the amount he earns, the former World Player of the Year is something of a luxury.
If he were to depart, Milan would reportedly bring in Lazzari as his replacement.
La Gazzetta dello Sport understands that Milan chief executive Adriano Galliani has already inquired about doing so in talks with Massimo Cellino, the Cagliari President.
Lazzari was among the players Massimiliano Allegri trusted in his two-year spell in Sardinia.
However, the pink paper believes that Milan's interest in Lazzari's teammate Alessandro Matri has been discouraged.
Cagliari would like to keep the prolific goalscorer at all costs even though his list of suitors is growing by the day.
