Sokratis has spoken about his “difficult” spell at Arsenal.
The Greek defender let the Gunners by mutual consent in January and is now with Olympiacos.
Sokratis, 32, played in 69 games for the Gunners over two-and-a-half years, but was exiled from Mikel Arteta’s squad at the start of the 2020-21 season.
“It was difficult because I didn’t have the chance to play because I wasn’t included in the squad list,” Sokratis told Football London.
“I had some offers to leave in the summer but it didn’t happen in the end and I accepted that I had to be outside the list. I did my training and I gave my best for the team, I was professional until the end.
“It was also difficult because in all my career I have played regularly. I played almost 70 games for Arsenal in two years, but when you are in a team you have to put the team first and yourself after.
“I accepted this, I was professional and I didn’t complain to anybody.”
