Bakayoko appeared twice in 31 Series A, he was lent to Milan during the 2017-18 campaign after he failed to impress Stamford Bridge.
Chelsea player Tiemoue Bakayoko is heard to return to AC Milan in the next transfer window.
The 25-year-old has set his sights on a second San Siro spell since he moved to Monaco, reported.
Due to the current financial environment, it is highly impossible for Monaco to convert the players’ loan spell into a permanent move though having the option.
Chelsea will have to lower its price in order to lure Milan into an offer, if they want to reach near to the £40 m they shelled out three years ago.
Over the years Bakayoko has been on his contract with the Blues.
