Costacurta believes that Modric's experience and desire will make him a valuable asset to the team, saying, "Someone as successful as him can always be decisive, even at his age. He has a winning spirit and a strong will to succeed, which is what makes him special."

Costacurta also praised San Siro, the home stadium of AC Milan, saying it's an exciting place to play, even for a seasoned player like Modric. He noted that playing in the stadium is a unique experience, and he was impressed by the welcome Modric received from the fans.

On a personal level, Costacurta trusts Zvonimir Boban, who has known Modric for a long time and speaks highly of him as a person and a player.

Regarding AC Milan's chances of winning the title, Costacurta is confident that it's a possibility. He believes that playing in the Champions League will be challenging for other teams, but AC Milan's schedule of playing once a week could give them an advantage.

Costacurta also thinks that the team's new coach, Max Allegri, brings a different energy to the team, which could be beneficial. He notes that the team's performance has improved since Allegri took over, with Rafael Leao showing a different level of focus and commitment.
