It was revealed on Wednesday that the club would be cancelling the contract of Greek defender Sokratis, who joined for a fee of around £17 million.
He found himself out of Mikel Arteta's plans this season and wasn't included in their 25-man Premier League squad.
Charles Watts has now listed a number of players Arsenal have let walk away - despite spending huge amounts of money on them.
The biggest name to have recently left the club is Mesut Ozil. Signed from Real Madrid for around £40 million in 2013, the playmaker arrived with a huge reputation.
Seen as such a valuable commodity, he signed a £350,000-per-week contract in January 2018.
Another attacker in the same vein was Alexis Sanchez, who arrived from Barcelona for £31.7 million in 2014.
Sanchez established himself as Arsenal's best player during his four-year stint, but would leave for bitter rivals Manchester United in a swap deal for Henrikh Mkhitaryan.
Mkhitaryan would move to Roma on a free transfer in 2020.
Santi Cazorla was ravaged by injury during his finals years in North London, but also departed on a free transfer to Villarreal.
Elsewhere in midfield, the duo of Jack Wilshere and Aaron Ramsey joined West Ham United and Juventus respectively.
While up front saw Danny Welbeck, who cost £16 million, signed for Watford.
Shkodran Mustafi is currently still at the club but isn't believed to be interested in renewing his contract.
The World Cup winner joined from Valencia in 2016 for a fee in excess of £35 million.
Mustafi even tweeted a message of support to international teammate Ozil, saying: "Bro, you have been the most unselfish player on and off the pitch, I have ever shared the dressing room with.
"You will be always remembered as the #AssistKing. Unfortunately we as a team haven't been able to assist you when you needed us the most. All the best."
Arsenal currently sit 10th in the league and return to action in the FA Cup against Southampton on Saturday.
