Arsenal have issued their retained list - with Yaya Sanogo the biggest name heading out the door.
The French forward made just two Premier League starts for the Gunners following his move from Auxerre in 2013.
Sanogo scored just one competitive goal during four years at the Emirates, spending time on loan at Crystal Palace, Ajax and Charlton instead.
His solitary strike in an Arsenal shirt came against Borussia Dortmund three years ago.
Sanogo joins youngsters Stefan O'Connor and Kristopher da Graca in heading out the door.
