The Arsenal striker, who has struggled to hold down a regular first-team place at the Emirates Stadium this season, suggests that he could move back to Germany in the future
The 28-year-old Germany international left his boyhood club to join the Gunners back 2012 although injury, that saw him miss the best part of the first four months of the 2013-14 season, has restricted him to just 13 appearances this term.
Despite not featuring in the Champions League last 16 defeat to Bayern Munich, Podolski did return to the side and play the full 90 minutes in the 4-1 win over Sunderland on Saturday and he admits he would consider a return to FC Koln later down the line.
He told Sky: "You can't exclude everything in football. FC [Koln] will be my club always and forever.
"You never know what's gonna happen in the next years."
Peter Stoger's Koln side are currently top of the second division in Germany having been relegated from the Bundesliga back in the 2011-12 season after finishing second from bottom.
Podolski, who was with FC Koln for 11 years during his first spell with the club before departing for Bayern Munich in 2006, still has a close affinity with his former side and was in attendance for their 1-1 draw with Greuther Furth on Monday.
