As the summer transfer window approaches, Pierre Kalulu has been one of the most sought-after young talents in Europe. The 21-year-old French defender is currently on loan from Paris Saint-Germain to Serie A club AC Milan.

Kalulu's move to Italy was announced by both clubs earlier this month, with the defender set to join the Rossoneri on a season-long loan deal. The move comes as a significant boost for AC Milan, who have struggled defensively this season under head coach Siniša Mihajlović.

The addition of Kalulu will provide the Rossoneri with a strong defensive presence in their backline, and he could make a significant impact in the coming months. The youngster has already impressed his new teammates during pre-season training, and it's clear that he'll be an important part of the team going forward.

In terms of updates on Kalulu's progress, there hasn't been much news available yet. However, it's likely that the young defender will continue to impress his new teammates and coaches, and that he'll make a positive contribution to AC Milan's defense.

Overall, the arrival of Pierre Kalulu at AC Milan is an exciting development for the club, and it's clear that he'll play an important role in helping them improve defensively this season. With his impressive performances in pre-season, it seems likely that the young defender will make a significant impact in the coming weeks and months.
