If it were me I will wait til the last minute, break this deal and go for someone like Antonio Silva if he is available next season. And left Milan in shamble. With a loan + obligation I can get him for a lower loan fee like 5-6m (compare to 14m+3m bonus) and left the headache for the next season after that, hopefully our financial keep getting better by then. The obligation I will give 40m paid in 5 financial years, with 20% clause of next profit. Slap 100m release clause in his contract
If he really become that world class defender after 2-3 years with us and someone activate that 100m clause, still getting 55m - 11m to Benfica (20%) =44m. Great business, basically feels like Dortmund with Haaland
