( 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 .
