(CNN) -- Lukas Podolski scored his first goal since returning to Cologne but it was not enough as they crashed to a defeat 2-1 against Schalke which leaves them bottom of the German Bundesliga.
Podolski celebrates his first goal since returning to Cologne, but it did not stop his side sliding to defeat.
The hosts had already gone behind to a second-minute Jefferson Farfan strike when Podolski, who rejoined his boyhood club from Bayern Munich in the summer, levelled matters with six minutes played.
But hopes Podolski's strike would inspire the home side fell flat a minute after half-time when Levan Kobiashvili scored a winner to move Schalke up to third in the table.
Defeat for Cologne leaves them rock bottom with just one point from their opening five games.
Schalke's early goal came courtesy of a corner to the far post where Gerald Asamoah was waiting to head the ball back across goal. Farfan was alert to the opportunity and sent his flying header into the back of the net for his second of the campaign.
The mood inside the RheinEnergie Stadion improved significantly four minutes later when Podolski latched onto a through-ball before coolly stepping around Manuel Neuer to stroke home.
The decisive moment in the game arrived just a minute after the interval when the dangerous Farfan attracted the home defence in the middle of the area before laying off a pass for Kobiashvili to thrash left-footed into the net.
Meanwhile, in the day's other Bundesliga match, Werder Bremen had the better of the chances but were held to a 0-0 draw by Hannover.
