According to reports, the Blues defender is on the verge of linking up with the Serie A club for the remainder of the season.
Chelsea boss Frank Lampard recently admitted that he was not averse to allowing the centre back to head out on loan this month.
Tomori has found himself further down the pecking order this season, with the summer signing of experienced Brazilian defender Thiago Silva squeezing the 23-year-old out of favour.
AC Milan have been the frontrunners to secure Tomori’s signature so far this transfer window and according to Italian website Mediaset, the Rossoneri are in pole position to get the deal over the line.
They claim an agreement for a loan move with an option to buy is on the verge of being completed, with Tomori set to finalise the deal either Tuesday or Wednesday this week.
The two clubs have done loan business in the not too distant past when Tiemoue Bakayoko had a spell at the San Siro for a season in 2018-19.
The details of the deal are believed to be a €3m loan fee with the option to buy stipulation in the contract set at €25m.
Tomori no doubt has a bright future in the game, highlighted in his performances at Stamford Bridge last season – but it remains to be seen if we see him back at Chelsea after this move goes through.
One player who has confirmed their departure from Stamford Bridge today is Danny Drinkwater.
The exiled midfielder has signed a loan deal with Turkish Super Lig side Kasimpaşa until the end of the season.
Drinkwater hasn’t played for Chelsea’s first team since featuring in the 2018 Community Shield against Manchester City.
