"I've just learned that Jackson Martinez has chosen AC Milan," Da Costa told Porto Canal.
"This is what he wants, I just want him to be happy. AC Milan will pay the €35 million [£25.3m] clause."
Martinez, who arrived from Chiaspas in 2012, scored 31 goals in all competitions for Porto last season, including eight in nine Champions League appearances.
