Arsenal have released Yaya Sanogo after an unsuccessful four-year spell at the Emirates Stadium.
The club confirmed the decision on Friday, with Sanogo, 24, having said earlier this week that his Arsenal "adventure is coming to an end." The striker's contract is expiring this summer.
Arsenal also said they are releasing three academy defenders -- Stefan O'Connor, Kristopher Da Graca and Kostas Pileas.
"We would like to take this opportunity to thank Yaya, Stefan, Kristopher and Kostas and wish them all the best for the future," the club said in a statement.
Arsene Wenger signed Sanogo on a free transfer in 2013 from Ligue 2 club Auxerre.
At the time he was a raw prospect, but was thrown straight into the first team as backup for Olivier Giroud and made 14 appearances in his debut season.
That included a surprising start against Bayern Munich in the Champions League after Giroud was dropped and in the FA Cup semifinal against Wigan.
But Sanogo struggled to progress from then on, in part because of a series of injuries that curtailed his development.
He leaves Arsenal with just one goal in 20 appearances, having gone on loan to three different clubs -- Crystal Palace, Ajax and Charlton -- while missing all of last season through injury.
O'Connor's only first-team appearance came in the Champions League in 2014 when he came on as a late substitute against Galatasaray. Da Graca and Pileas never played for the senior team.
