Arsenal London head coach Mikel Arteta is concerned about the quality of play of his team's Ukrainian defender Oleksandr Zinchenko in recent matches.
At the same time, the 27-year-old footballer suffered an injury, due to which he missed the last match of his team.
As a result, according to the Express, Arteta is seriously considering a decision on the early return of Kieran Tierney from loan at Real Sociedad to replace Zinchenko.
