The negotiations had been dragging on for a while, with the Mexico international informed he was not part of Ruben Amorim’s plans for this season.
His preferred option was always Porto, where he has a strong admirer in coach Francesco Farioli, but working out the terms proved difficult.
Gimenez breakthrough with FC Porto
According to sources including Milan expert Daniele Longo transfer pundit Fabrizio Romano Sky Sport Italia and Sportitalia, the deal was done late Saturday evening.
The key to the breakthrough was introducing clauses making the option to buy into an obligation, with conditions including the number of appearances Gimenez makes for the club.

There is no loan fee, but the option to buy is set at €18m plus €2m add-ons.
Milan had paid over €30m to buy Gimenez from Feyenoord in January 2025, but after an initially strong start, he floundered amid poor form and injuries, including ankle surgery in December 2025.
He leaves the Rossoneri with seven goals and six assists in 37 competitive games.
