Arsenal boss Mikel Arteta admits the club are in negotiations to terminate Shkodran Mustafi's contract this month.
The German defender, whose contract expires in the summer, has not played since Boxing Day.
And it appears Mustafi will follow Sokratis and Mesut Ozil in being allowed to leave the Emirates immediately.
"Again, it's another situation at the moment that is open," Arteta said in his press conference ahead of the Gunners clash with Manchester United on Saturday.
"We are having conversations internally, with player and agent. We will see what is the right solution for this moment."
