According to a report from Calciomercato, Milan will be eager to try and get a lower price than the €28 million buy-out clause that Chelsea have put on the English defender.
Chelsea manager Thomas Tuchel wants to have Tomori back at the club next season, but if he has to let him go, he wants to get as much as possible from his departure.
As a result, the Rossoneri will need to raise up €28 million, which is set to be done through the sales of two defenders in particular.
As things stand, the pair could be back at Milan in the summer, with Atalanta yet to exercise their €16 million option to buy, given that Caldara has not played as much as they would have intended, whilst Parma will have to pay €7 million for Conti if they stay up, but they are still in the relegation zone.
The money raised from the sales of Caldara and Conti could go a long way into helping Milan secure a permanent deal for Tomori, who has impressed at the San Siro.
Tomori has played in 12 games in all competitions for Milan since joining in January, which is more than Caldara and Conti have played ever since they joined their respective clubs, with both of them playing just eight times since they joined their loan clubs.
