Inter Milan stars Yann Bisseck, Piotr Zielinski, and Davide Frattesi have reportedly returned to training from injuries.

According to Corriere dello Sport via FCInterNews, the fitness situation at Appiano Gentile is massively improving.

New manager Cristian Chivu was without numerous first-team stars during Inter’s 2025 FIFA Club World Cup campaign.

Indeed, all three aforementioned players were out of the squad.

Furthermore, Chivu was unable to call upon Hakan Calhanoglu, who was at the time the subject of intense transfer speculation.

As Inter aim to recover from last season’s heartbreak, pre-season preparations ramp up with a focus on fitness.

Recurring injuries to several key first-team elements resulted in Inter’s only trophyless season under Simone Inzaghi last term.

Therefore, Chivu doesn’t want to repeat the same mistake.

Instead, he focuses on carefully managing workloads and keeping the squad healthy.

However, some players are just coming back from injuries.

Yann Bisseck and Piotr Zielinski have recently rejoined the squad.

Now, Davide Frattesi looks set to resume training after recovering from abdominal surgery.
