The Arsenal manager has been forced to re-think the German's future ahead of Wednesday's clash with Besiktas after Olivier Giroud was ruled out for 10 weeks with a foot injury.
The German had been told he was free to leave the Emirates Stadium before the close of the transfer window, but an injury to Olivier Giroud has prompted a reverse of that idea.
Juventus and Wolfsburg were among the clubs interested in signing Podolski.

"Podolski is in the squad tomorrow and will stay with us," said the Frenchman ahead of the second leg of his side's Champions League qualifier with Besiktas.
Giroud will be unavailable until November, with scans by a specialist on Tuesday confirming a broken bone in the France striker's foot and the equalizer he scored as the Gunners came from behind to draw 2-2 against Everton is expected to be his last first-team action for 10 weeks.
Podolski's immediate position under Wenger has further been strengthened by doubts over Alexis Sanchez's fitness for Wednesday night's clash with the Turkish side at the Emirates Stadium.
Wenger also has Yaya Sanogo and Joel Campbell to turn to in attack in Giroud's absence but neither boasts Podolski's experience in Europe's elite competition.
