Having unable to nail down a regular spot under Frank Lampard during the first half of the 2020-21 season, the centre-back secured a six-month loan move to San Siro, where he established himself as a first-team regular.
Tomori racked up 17 Serie A appearances as the Rossoneri secured a return to the Champions League, with manager Stefano Pioli and technical director Paolo Maldini both confirming their intentions to keep the 23-year-old defender on the books permanently.
According to transfer expert Fabrizio Romano, the 18-time Serie A champions have agreed to fork out £25m to sign the centre-back, and he is now ready to put pen to paper on a five-year contract in Italy.
