Cologne maintained their battle to avoid relegation from the Bundesliga with a 1-1 draw at home to Stuttgart, who equalised through Cacau after Slawomir Peszko's opener.
Cologne rebounded from their heavy defeat by Borussia Dortmund last weekend with a convincing 3-0 win over ten-man Augsburg as Lukas Podolski scored twice before Slawomir Peszko netted the third.
Slawomir Peszko has become Cologne's latest signing of the January transfer window, with the Lech Poznan midifelder moving to the Bundesliga on loan until the end of the season.
