The team will travel to Paris later today to face PSG after their 1-0 loss in the first leg at the Emirates Stadium. Odegaard, who injured his foot in the final minutes of their Premier League match against Bournemouth, has made a quick recovery and is back to full training.
Timber, who missed the Bournemouth game, is unlikely to participate in the Champions League semi-final, but Arteta will be pleased to see him back on the training pitch. Calafiori, who has been recovering from a knee injury, has also resumed training and may be considered for selection if needed.
Arteta will likely face questions about the trio's availability for the starting lineup during his press conference tomorrow. Meanwhile, PSG has also received good news, as winger Ousmane Dembele has been cleared to play after being rested for their league game against Strasbourg.
