According to reports, Chelsea are willing to let Tiemoue Bakayoko leave the club, but not for less than £19m.
AC Milan have been credited with interest during this summer's transfer window, but they would want him on a lesser price-tag.
The 25-year-old has been on loan from the Blues for the last two seasons, representing Milan during the 2018-19 campaign before returning to Monaco, making 23 appearances in his second spell with the club.
According to Gazzetta dello Sport, the Frenchman is prepared to take a 50% pay cut in order to secure a permanent move to San Siro ahead of the 2020-21 season.
Ligue 1 champions Paris Saint-Germain are reportedly also interested in Bakayoko.
