Arsenal have a Deadline Day decision to make over the future of Ethan Nwaneri after an approach from Borussia Dortmund.
Standard Sport understands that the German club are keen on signing the 19-year-old on a season-long loan deal.
Deadline Day live! All the latest transfer news and rumours
With Giannis Konstantelias suffering an ACL injury on his Bundesliga debut, Dortmund have identified Nwaneri as a potential replacement.
Dortmund wanted to sign the teenager last summer on a permanent deal when his future was also in doubt, but Nwaneri ultimately opted to sign a new contract at Arsenal.
After an unsuccessful loan spell at Marseille, Nwaneri returned to Arsenal in May and his place at the club has remained uncertain.
Mikel Arteta has indicated a willingness to let him leave in order to play regularly and develop. It is understood that Arsenal are open to a loan move rather than a permanent exit.
Dortmund are hoping to get the green light to secure Nwaneri on Deadline Day but the ball is in Arsenal's court.
The numbers in attack are already being trimmed, with Gabriel Martinelli, Gabriel Jesus and Fabio Vieira all expected to seal moves away before the window shuts.
Leandro Trossard departed earlier in the summer too and Christos Tzolis has been the only signing in forward areas.
Despite those outgoings, Arsenal's strength in depth meant that Nwaneri did not make the matchday squad for the win over Aston Villa on Monday night.
Bukayo Saka, Noni Madueke and Max Dowman are all ahead of Nwaneri in the pecking order of Arteta's options on the right wing and there is an awareness at the club that his minutes are likely to remain limited.
With Eberechi Eze potentially set to be used more as a left winger this season, there could be opportunities for Nwaneri to deputise for Martin Odegaard in a central position.
However, Mikel Merino, Bruno Guimaraes and Martin Zubimendi all came on against Villa to emphasise how strong Arsenal's midfield ranks are.
