Everton striker Moise Kean is being linked with a return to Serie A.
The 19-year-old has made 10 appearances for Everton since joining from Juventus in the summer, starting twice in the Premier League.
But he is yet to score as he adjusts to life in England.
Calciomercato says Milan are monitoring his situation and aren't ruling out a January move for the forward.
Everton splashed out £25m on his signing less than three months ago.
