After adding goalkeeper Mike Maignan to their ranks, the Rossoneri complete another transfer ahead of the 2021/22 season.
AC Milan have secured the signing of Fikayo Tomori on a permanent basis from Chelsea.
Milan originally brought in Tomori on a season-long loan deal last summer with an option to convert it into a permanent move for £25 million.
The 23-year-old defender made 22 appearances across all competitions last season, helping Stefano Pioli’s men secure a second-place league finish and qualify for the Champions League after an eight-year break.
The Serie A side have now exercised their option to buy the England international, who commits to a four-year deal at the club.
An official statement on the club website read: “AC Milan is delighted to announce the exercising of the option for the permanent transfer of Oluwafikayomi Oluwadamilola Tomori from Chelsea.
“The English defender, who made 22 appearances and scored one goal over the last season, will continue to play with the Club until 30 June 2025.”
A statement on the Chelsea website read: “Fikayo Tomori will complete a permanent transfer from Chelsea to AC Milan on 1 July.
“The Chelsea Academy graduate had been with the Blues since Under-8s level and made 27 first-team appearances for the club in total, scoring two senior goals.
“Tomori enjoyed great success with Chelsea at youth level, winning the FA Youth Cup and UEFA Youth League, scoring in both finals, in addition to being named our Academy Player of the Year in 2016.
“Chelsea is grateful to Fikayo for his contributions at the club, from youth level to men’s first-team squad, and wishes him the very best in his future career.
