Speaking to German newspaper Bild, Podolski said: "I've always felt comfortable there. With the fans, with the team and also with the manager. I'm going back to play, I have to say my qualities suit Arsenal.
"Inter? Last season went how it went. English football is the one which best suits my style, but I know how suddenly everything can change.
"I have characteristics to help different teams, but it was a mistake to go to Inter with no redemption clauses.
"In football there are times when everything doesn't work out for the best. You're not always playing as a starter, and you just have to accept the decisions and work on your own game.
"That's what I did, but now I'm looking forward."
