Podolski has made 14 Bundesliga appearances for the Rhine side this season, bagging 14 goals and recently asked for more time to think over his contract with Koln, which is due to expire in 2013.
"I rule out nothing. Especially not in Cologne, because Cologne is not normal," Solbakken told Bild. We need a 'Plan B' and have to look at what we can do after Poldi's decision."
Cologne are bent on keeping the former Bayern Munich man in the team, with Arsenal, Lazio, Lokomotiv Moscow and Schalke reportedly interested in the player.
While Podolski's agent confirmed that his client will not leave during the winter, Cologne may be forced to let him go in the summer if he decides to decline a contract extension.
