The Germany international joined the Nerazurri on a temporary basis for the second half of the season, with the hopes of revatilising his footballing career.
However, after 17 league appearances with just one goal in Italy, Podolski conceded it was a mistake to join Inter and is determined to prove his worth at Arsenal.
"I’ve always felt comfortable there [at Arsenal]," he told German publication Bild. "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."
