I can only provide limited information from the search result available. The source [1] contains only a headline and a brief snippet stating that **Piero Hincapie and Riccardo Calafiori** returned to Arsenal training and were seen with the squad in open training. However, based on related injury updates from the same period [2], here is context about these players: **Piero Hincapie** limped off during Arsenal's draw against Liverpool on January 8 after suffering a minor groin injury to his left leg. His return timeline was initially uncertain, with doubts about his availability for the Inter Milan match. **Riccardo Calafiori** had been sidelined after feeling something awkward before the Liverpool game and had not reappeared since. His expected return was projected for the start of February. The news of both players returning to training represents a significant boost for manager **Mikel Arteta**, particularly as Arsenal prepared for their Champions League encounter against Inter Milan. Their availability would strengthen the defensive options for the club during a demanding period of fixtures. --- **Note:** The full article at the provided link is not accessible through the search results—only the headline and initial sentence are available.
