The Argentine striker's representative believes that his charge has done more than enough to impress, despite not featuring regularly for the Rossoneri
The Catania-owned striker signed for the Rossoneri in January on a six-month loan with a view to a permanent deal, as the Rosoneri were keen to bolster their attacking options following Antonio Cassano's heart surgery.
The Argentine has only made eight Serie A appearances for Milan, but his agent is confident that the former Barcelona forward has convinced the Italian champions to exercise their buying option.
"He will stay at Milan, because he has shown in the few minutes he has been given in matches and in practice sessions that he is a great player and a true champion," Andrea D'Amico told Radio Lombardia.
"He has physical strength, class and finishing prowess, which is something that is not easy to find."
Milan, who are one point behind leaders Juventus in the Serie A table, will host Bologna on Sunday.
