Academy defender Marli Salmon trained with the Arsenal first-team squad today.
The centre-back has returned to Arsenal after being at the U17 World Cup with England.
Salmon, who was a late callup for the tournament, didn’t get any playing time in Qatar.
He could be involved when Arsenal U19s host Bayern Munich in the UEFA Youth League tomorrow.
The first-team are also in action against the same opponents in the Champions League, with Martin Odegaard back in training.
Alex Oxlade-Chamberlain is continuing to train with Arsenal’s U21 squad, which includes Archie Stevens and Cam’ron Ismail.
