Milan will need to spend €14m to get Morgan Schneiderlin from Manchester United in January.
The Rossoneri are known to be seeking reinforcements in midfield and are in the process of a takeover by Chinese investors.
According to The Mirror newspaper, any club trying to get Schneiderlin mid-season will have to pay in the region of €14m.
The 27-year-old France international left Southampton for Manchester United in July 2015 for €35m.
However, he has dropped down the pecking order at Old Trafford under Jose Mourinho.
There are several Manchester United players who are attracting interest from Serie A sides, including Matteo Darmian and Memphis Depay.
