Tottenham midfielder Sandro is a summer transfer target for both Milan giants.
Corriere dello Sport says Inter Milan have been keeping tabs on Sandro for much of this season and now AC Milan are also involved.
Sandro has been in and out of the Spurs line-up since shaking off his injury problems and is open to a move to Italy.
While Inter have already been in contact with the player's camp, Milan are now also preparing their pitch as they plan to overhaul their aging midfield this summer.
