Inter Milan is getting ready to make an offer for Oleksandr Zinchenko in January.
Mikel Arteta is thought to be "open-minded" about allowing the Ukrainian to depart.
At the Emirates, former Manchester City star Zinchenko has fallen in the hierarchy.
Zinchenko, according to Inter, may significantly improve their domestic campaign.
With just two appearances in the Premier League this season, Zinchenko could be following Tierney out the door when the player's agreement ends at the completion of the season. Tierney will be departing the team on a free transfer.
