The English defender spent last season on loan at the San Siro and the Serie A giants activated an option-to-buy clause in their contract with Chelsea which saw Tomori join the club this summer for a fee of £28.5m.
That fee makes Tomori one of the most expensive English central defenders of all-time but the defender insists he’s comfortable with the price tag.
