The Brazilian defender could sign for Los Che today.
The left-back is in the final year of his contract at Emirates Stadium and is assessing his options after being told his opportunities would be limited.
Perez is in a similar situation with his agent repeatedly voicing his frustration at Arsenal's unwillingness to take a significant hit on the £17m they paid Deportivo La Coruna to sign him just over a year ago.
Deportivo are interested in re-signing the striker but the two clubs remain a long way apart in their valuations. Newcastle's attempt to take Perez on loan was rejected with the Gunners demanding a permanent transfer.
