Real Sociedad are set to unveil new signing Nacho Monreal on Monday.
The left-back will sign a two-year deal with the Basque side and will be officially unveiled on Monday.
The Spanish international has spent seven years in the Premier League with the Gunners and will cost La Real very little money.
Monreal is expected to be at Arsenal's north London derby with Tottenham Hotspur on Sunday but in a watching capacity, rather than on the pitch as he says goodbye to the Emirates Stadium.
La Real's director of football, Roberto Olabe, wanted to bring Monreal to Anoeta last summer, but he's finally got his man this time around.
